refactor: 移除本地前端容器，仅保留远程部署

本地前端因 Casdoor OAuth 回调固定指向 onu.dhdx.fun，无法完成
登录流程，没有实际用途。转为仅远程服务器部署。

本地服务器现仅需 2 容器：backend + celery-worker(含beat)

-- **Service 层**：业务逻辑，不直接操作数据库
-- **Model 层**：SQLAlchemy 模型定义
-- **异步任务**：耗时操作使用 Celery
-
-#### 前端架构
-- **组件分类**：
-  - `components/common/`：通用组件
-  - `components/business/`：业务组件
-  - `views/`：页面组件
-- **状态管理**：使用 Pinia stores
-- **API 调用**：统一在 `api/` 目录封装
-
-### 安全规则
-
-#### 数据安全
-- SSH 密码必须加密存储（使用 Fernet 加密）
-- 敏感信息通过环境变量配置
-- 数据库连接使用 SSL
-- 定期备份数据（90天历史记录）
-
-#### 应用安全
-- 所有 API 端点需要认证（除登录接口）
-- 实现 CSRF 保护

-
-#### 缓存策略
-- Redis 缓存热点数据（设备状态）
-- 缓存过期时间：30分钟
-- 手动刷新有5分钟冷却限制
-
-#### 异步处理
-- SSH 状态检查使用 Celery 异步任务
-- 批量导入使用后台任务
-- 定时任务使用 Celery Beat
-
-### 开发规则
-
-#### 提交前清理
-- 每次提交前必须清理项目中不需要的文件
-- 包括：测试文件（`test_*.py`）、调试脚本、不再使用的 shell 脚本、冗余 markdown 文档
-- 检查是否有硬编码的敏感信息（密码、密钥、token）
-- 检查 `.gitignore` 是否覆盖了所有不应提交的文件（`*.pem`、`.env`、`__pycache__` 等）
-
-#### 环境配置
-- 开发环境使用 `.env.development`
-- 生产环境使用 `.env.production`
-- 不提交 `.env` 文件到 Git
-- 提供 `.env.example` 模板
-- 敏感信息（数据库密码、Casdoor 密钥等）仅通过环境变量注入
-
-#### 测试要求
-- 核心业务逻辑需要单元测试
-- API 端点需要集成测试
-- 测试覆盖率目标：≥80%
-
-#### 文档要求
-- API 变更及时更新 Swagger 文档
-- 复杂业务逻辑添加注释
-- 重要配置添加说明
-
-### 部署规则
-
-#### Docker 部署
-- 使用 Docker Compose 编排
-- 外部 PostgreSQL 和 Redis（不在容器内）
-- 日志挂载到宿主机
-- 使用 Nginx 反向代理
-
-#### 环境变量
-必需配置：
-- `DATABASE_URL`：PostgreSQL 连接字符串
-- `REDIS_URL`：Redis 连接字符串
-- `CASDOOR_*`：Casdoor 认证配置
-- `SECRET_KEY`：应用密钥
-
-#### 监控告警
-- 健康检查端点：`/health`
-- 性能指标端点：`/metrics`
-- 日志级别：生产环境使用 INFO

-
-## 部署陷阱与经验教训
-
-### 修改代码后必须重新构建镜像
-
-**问题**：修改了宿主机上的源码后，直接 `docker compose up -d` 或 `docker compose restart` **不会**让容器使用新代码。容器运行的是构建时打包进镜像的旧代码。
-
-**正确流程**：
-```bash
-# 1. 重新构建镜像（必须加 --no-cache 确保不用旧层）
-docker compose build --no-cache backend   # 或 frontend，或两者
-
-# 2. 重新创建容器（必须用 rm + up，或 up --force-recreate）
-docker compose rm -f backend
-docker compose up -d backend
-
-# 3. 如有数据库模型变更，执行迁移
-docker compose exec backend alembic upgrade head
-```
-
-**不要用**：
-- `docker compose restart`：只重启进程，不更新镜像
-- `docker compose up -d`（无 build）：容器配置变了会重建，但镜像不变
-
-### 端口被占用导致容器启动但无端口映射
-
-**问题**：如果宿主机端口已被其他容器占用，新容器会启动成功（`docker compose up` 不报错），但端口映射为空 `{}`，外部无法访问。
-
-**排查方法**：
-```bash
-# 检查端口映射是否正常
-docker inspect <container> --format '{{json .NetworkSettings.Ports}}'
-
-# 查看谁占用了端口
-docker ps | grep <port>
-```
-
-**解决方法**：先停掉占用端口的旧容器，再 `docker compose rm -f && docker compose up -d`。
-
-### frontend 容器必须配置 VITE_API_PROXY_TARGET
-
-**问题**：根目录 `docker-compose.yml` 的 frontend 服务如果没有配置 `VITE_API_PROXY_TARGET`，Vite 代理会默认打到 `http://localhost:8001`，导致所有 `/api` 请求 500 或无法到达后端。
-
-**必须在 docker-compose.yml 中配置**：
-```yaml
-frontend:
-  build: ./frontend
-  ports:
-    - "5173:5173"
-  environment:
-    - VITE_API_PROXY_TARGET=http://backend:8000
-```
-
-### 新增数据库模型后必须执行迁移
-
-**问题**：新增了 SQLAlchemy 模型（如 `DeviceDailySnapshot`、`SystemSetting`），重建镜像后如果不执行 `alembic upgrade head`，表不存在会导致 500 错误。
-
-**每次新增模型的完整流程**：
-```bash
-# 1. 创建迁移文件（在宿主机或容器内）
-docker compose exec backend alembic revision --autogenerate -m "描述"
-
-# 2. 重建镜像
-docker compose build --no-cache backend
-
-# 3. 重启容器
-docker compose rm -f backend && docker compose up -d backend
-
-# 4. 执行迁移
-docker compose exec backend alembic upgrade head
-```
-
-### Alembic 迁移文件 revision ID 不能重复
-
-**问题**：手动创建迁移文件时，如果 `revision` 字段与已有文件重复，`alembic upgrade head` 会报 `Multiple head revisions are present` 错误。
-
-**规则**：手动创建迁移文件时，revision ID 使用不与现有文件冲突的唯一字符串（如 `h8i9j0k1l2m3`），并确认 `down_revision` 指向正确的上一个版本。
-
-### Celery worker 必须重建才能识别新任务
-
-**问题**：新增 Celery 任务模块后，如果只重建 backend 而不重建 celery-worker，worker 不会注册新任务，消息会被丢弃并报 `KeyError`。
-
-**规则**：新增任务模块后，backend 和 celery-worker 都必须重建：
-```bash
-docker compose build --no-cache backend celery-worker
-docker compose rm -f backend celery-worker
-docker compose up -d backend celery-worker
-```
-
-验证任务是否注册：
-```bash
-docker compose exec celery-worker celery -A celery_worker.celery_app inspect registered
-```
-
-### 区域管理员多区域过滤必须用 `.in_()` 而非 `==`
-
-**问题**：`assigned_area` 字段存储逗号分隔的多个区域（如 `"城区,郊区"`），用 `==` 只能匹配整个字符串，导致多区域管理员只能看到第一个区域的数据。
-
-**规则**：所有涉及 `assigned_area` 的过滤都必须先 split 再用 `.in_()`：
-```python
-areas = [a.strip() for a in current['assigned_area'].split(',') if a.strip()]
-query = query.filter(Model.region.in_(areas))
-```
-
-### Vite dev server 通过反向代理访问需配置 allowedHosts
-
-**问题**：通过域名反向代理访问 Vite dev server 时，会报 `Blocked request. This host is not allowed`。
-
-**解决**：在 `vite.config.js` 中设置：
-```js
-server: {
-  allowedHosts: ['all', 'your-domain.com'],
-}
-```
-
-### iOS PWA standalone 模式与 Safari 的 safe area 差异
-
-**问题**：`env(safe-area-inset-top)` 在 Safari 浏览器中为 0（有地址栏占位），在 standalone 模式（添加到主屏幕）下为真实刘海高度（44-59px）。直接使用会导致 Safari 中布局正常但 standalone 中顶栏/弹窗重叠。
-
-**规则**：所有 safe area 相关样式必须包在 `@media (display-mode: standalone)` 中，Safari 不受影响：
-```css
-@media (display-mode: standalone) {
-  .mobile-topbar {
-    height: calc(52px + env(safe-area-inset-top));
-  }
-}
-```
-
-`ElMessage` 的 offset 通过 `src/utils/message.js` 封装统一处理，所有页面从该文件导入而非直接从 `element-plus` 导入。
-
-### Docker healthcheck 镜像内无 curl
-
-**问题**：backend 镜像基于 Python slim，没有 `curl`，healthcheck 用 `curl` 会导致所有依赖服务启动失败。
-
-**规则**：healthcheck 使用 Python 内置模块：
-```yaml
-healthcheck:
-  test: ["CMD", "python3", "-c", "import urllib.request; urllib.request.urlopen('http://localhost:8000/health')"]
-  interval: 15s
-  timeout: 10s
-  retries: 5
-  start_period: 40s
-```
-
-### More 分页标记清除不能使用 `[^\n]*` 删除整行
-
-**问题**：`_clean_output` 中 `---- More ----[^\n]*` 会将 `---- More ----` 及其后同行所有内容删除。当 OLT 输出的 More 提示与下一页第一条设备数据出现在同一行时（如 `---- More ----\r\r 1484-778f-aa60 ...`），该设备行会被错误丢弃，导致部分设备扫描不到。
-
-**规则**：仅移除 More 标记文本本身，保留同行后续内容：
-```python
-# 错误：删除整行
-output = re.sub(r'---- More ----[^\n]*', '', output)
-
-# 正确：仅移除标记文本
-output = re.sub(r'---- More ----', '', output)
-```
-
-此问题在 OLT `172.16.0.18`（大化县新城初中）上发现：93 台设备仅解析出 90 台，丢失 3 台。

-## 核心业务逻辑
-
-### SSH 状态检查流程
-1. 从数据库获取 OLT 设备配置
-2. 建立 SSH 连接（使用连接池）
-3. 执行命令：`display onu slot {slot_number}`
-4. 解析返回结果：
-   - 包含 "Up" → 在线
-   - 包含 "Offline" → 离线
-5. 更新设备状态到数据库
-6. 记录历史状态
-
-### 权限控制逻辑
-- **超级管理员**：所有权限
-- **管理员**：管理所有设备和用户
-- **区域管理员**：管理指定区域的设备
-- **学校管理员**：管理指定学校的设备
-- **普通用户**：只读权限
-
-### 数据导入流程
-1. 上传 Excel 文件
-2. 使用 Pandas 解析数据
-3. 数据验证（MAC 地址格式、必填字段）
-4. 批量插入数据库
-5. 返回导入结果（成功/失败记录）
-
----
-
-## 开发指南
-
-### 快速启动
-
-**Docker 部署（推荐）**：
-```bash
-# 1. 配置环境变量
-cp backend/.env.example backend/.env
-# 编辑 .env 填入实际配置
-
-# 2. 启动所有服务
-docker compose up -d
-
-# 3. 初始化数据库
-docker compose exec backend python scripts/init_db.py
-```
-
-**本地开发**：
-```bash
-# 后端
-cd backend
-python -m venv venv && source venv/bin/activate
-pip install -r requirements.txt
-uvicorn app.main:app --reload --host 0.0.0.0 --port 8000
-
-# 前端
-cd frontend
-npm install && npm run dev
-
-# Celery Worker
-cd backend
-celery -A celery_worker.celery_app worker --loglevel=info
-
-# Celery Beat
-cd backend
-celery -A celery_worker.celery_app beat --loglevel=info --schedule=/tmp/celerybeat-schedule
-```
-
-### 数据库迁移
-
-```bash
-# 创建迁移
-alembic revision --autogenerate -m "描述"
-
-# 执行迁移
-alembic upgrade head
-
-# 回滚
-alembic downgrade -1
-```
-
-### 添加新功能
-
-1. **后端 API**：
-   - 在 `app/api/v1/` 创建路由文件
-   - 在 `app/services/` 创建服务文件
-   - 在 `app/schemas/` 定义请求/响应模式
-   - 在 `app/models/` 定义数据模型（如需要）
-
-2. **前端页面**：
-   - 在 `views/` 创建页面组件
-   - 在 `api/` 添加 API 调用
-   - 在 `router/` 添加路由配置
-   - 在 `stores/` 添加状态管理（如需要）
-

-## MCP Tools: code-review-graph
-
-**IMPORTANT: This project has a knowledge graph. ALWAYS use the
-code-review-graph MCP tools BEFORE using Grep/Glob/Read to explore
-the codebase.** The graph is faster, cheaper (fewer tokens), and gives
-you structural context (callers, dependents, test coverage) that file
-scanning cannot.
-
-### When to use graph tools FIRST
-
-- **Exploring code**: `semantic_search_nodes` or `query_graph` instead of Grep
-- **Understanding impact**: `get_impact_radius` instead of manually tracing imports
-- **Code review**: `detect_changes` + `get_review_context` instead of reading entire files
-- **Finding relationships**: `query_graph` with callers_of/callees_of/imports_of/tests_for
-- **Architecture questions**: `get_architecture_overview` + `list_communities`
-
-Fall back to Grep/Glob/Read **only** when the graph doesn't cover what you need.
-
-### Key Tools
-
-| Tool | Use when |
-| ------ | ---------- |
-| `detect_changes` | Reviewing code changes — gives risk-scored analysis |
-| `get_review_context` | Need source snippets for review — token-efficient |
-| `get_impact_radius` | Understanding blast radius of a change |
-| `get_affected_flows` | Finding which execution paths are impacted |
-| `query_graph` | Tracing callers, callees, imports, tests, dependencies |
-| `semantic_search_nodes` | Finding functions/classes by name or keyword |
-| `get_architecture_overview` | Understanding high-level codebase structure |
-| `refactor_tool` | Planning renames, finding dead code |
-
-### Workflow
-
-1. The graph auto-updates on file changes (via hooks).
-2. Use `detect_changes` for code review.
-3. Use `get_affected_flows` to understand impact.
-4. Use `query_graph` pattern="tests_for" to check coverage.

-# 为 H3ConuMS2 添加 ONU 远程重启 & 光功率查询功能 — 后端开发指南
-
-> 目标：将 H3C iMC 平台的 ONU 远程重启和光功率查询功能集成到 H3ConuMS2 项目中
-> 技术栈：FastAPI + SQLAlchemy + requests (HTTP Digest Auth)
-> 源项目参考：`/home/v6ole/pyproject/H3ConuMS`
-
----

-## 1. 整体架构
-
-```
-┌──────────────────┐      REST API 调用       ┌──────────────────┐

-```
-
-**后端提供的 API 端点：**
-| 端点 | 方法 | 说明 | iMC 后端接口 |
-|------|------|------|-------------|
-| `/api/devices/{id}/reboot` | POST | 远程重启 ONU | `/imcrs/epon/onu/reboot?mac={mac}` (POST) |
-| `/api/devices/{id}/optical-power` | GET | 获取 ONU 光功率 | `/imcrs/epon/onu/onuLightWaneInfo?mac={mac}` (GET) |
-
-**数据流（以重启为例）：**
-1. 客户端 POST `/api/devices/{id}/reboot`
-2. 后端控制器验证设备存在 + 权限 → 调用 `IMCService.reboot_onu()`
-3. `IMCService` 构建 HTTP Digest 认证头 → POST 到 iMC REST API
-4. iMC 返回结果 → 后端解析错误码 → 返回 JSON
-
----
-
-## 2. Digest 认证原理解析
-
-iMC 的 REST API 使用 **HTTP Digest Access Authentication**（RFC 2617），不是普通的 Cookie/Session 登录。
-
-### 认证流程

-
-### 核心 MD5 计算
-
-```python
-cnonce = md5(str(time.time())).hexdigest()[:16]
-ha1 = md5(f"{username}:{realm}:{password}").hexdigest()
-ha2 = md5(f"{method}:{uri}").hexdigest()
-response = md5(f"{ha1}:{nonce}:{nc:08d}:{cnonce}:auth:{ha2}").hexdigest()
-```

-
-| 文件 | 操作 | 说明 |
-|------|------|------|
-| `backend/app/services/imc_service.py` | **新增** | iMC API 服务（Digest 认证 + 重启 + 光功率） |
-| `backend/app/services/__init__.py` | 修改 | 导出 IMCService |
-| `backend/app/schemas/device.py` | 修改 | 添加重启/光功率响应 Schema |
-| `backend/app/api/v1/devices.py` | 修改 | 添加重启和光功率 API 路由 |
-| `backend/app/core/config.py` | 修改 | 添加 iMC 配置项 |
-| `.env` 或 `backend/.env` | 修改 | 添加 iMC 环境变量 |

-## 5. 关键陷阱与注意事项
-
-### ⚠️ Digest 认证的 nonce 过期问题
-
-iMC 的 nonce 有有效期（通常 5-10 分钟）。过期后服务器返回 **401**。
-- 代码中 `_clear_auth()` 清空 nonce，下次请求自动重新握手
-- 重启和光功率方法都在 for 循环中捕获 401 并 `continue` 重试
-
-### ⚠️ MAC 地址格式
-
-iMC REST API 要求 MAC 地址格式为 **1484-7790-4840**（连字符分隔，大写十六进制）。
-如果数据库存储格式不同，需要做格式转换：
-
-```python
-def normalize_mac(mac: str) -> str:
-    """标准化 MAC 为 iMC 要求的格式：1484-7790-4840"""
-    clean = mac.replace(':', '').replace('-', '').replace('.', '').upper()
-    return f"{clean[0:4]}-{clean[4:8]}-{clean[8:12]}"
-```
-
-### ⚠️ 重启接口需要 Content-Length: 0
-
-即使请求体为空，也必须显式设置 `Content-Length: 0` 头，否则 iMC 会报错。
-
-### ⚠️ 光功率接口返回空数据的情况
-
-当 ONU 离线或光模块故障时，iMC 返回的 `powerIn` / `powerOut` 可能是 `" --"`（两个空格+两个横线）或 `None`。前端需做占位符处理。
-
-### ⚠️ 重启操作较慢
-
-从发起请求到设备实际重启完成约需 **30-60 秒**（取决于 SNMP 响应）。建议：
-- 前端按钮显示 loading 状态
-- 后端设置合理超时（connect=5s, read=20s）
-- 不要在短时间内对同一设备重复操作
-
-### ⚠️ 并发控制
-
-建议对重启操作添加简单的并发控制，避免同一设备被多次重启：
-
-```python
-import threading
-
-_reboot_locks = {}
-_reboot_lock = threading.Lock()
-
-def reboot_onu(self, mac):
-    with _reboot_lock:
-        if mac not in _reboot_locks:
-            _reboot_locks[mac] = threading.Lock()
-    lock = _reboot_locks[mac]
-
-    if not lock.acquire(blocking=False):
-        return {"success": False, "message": "该设备正在重启中，请稍后"}
-    try:
-        # ... 重启逻辑 ...
-    finally:
-        lock.release()
-```
-
-### ⚠️ Docker 部署注意
-
-- 在 `docker-compose.yml` 的 `backend` 服务中新增环境变量：
-  ```yaml
-  environment:
-    - IMC_API_URL=https://172.16.1.252:8443
-    - IMC_API_USERNAME=admin
-    - IMC_API_PASSWORD=Pwd@12345
-    - IMC_API_VERIFY_SSL=false
-  ```
-- `backend` 和 `celery-worker` 容器都需要这些变量
-- 修改后必须重新构建镜像：
-  ```bash
-  docker compose build --no-cache backend
-  docker compose rm -f backend && docker compose up -d backend
-  ```

-## 6. 测试验证
-
-### 手动测试
-
-```bash
-# 1. 重启设备
-curl -X POST "http://localhost:8000/api/devices/1/reboot" \
-  -H "Authorization: Bearer <token>"
-
-# 2. 获取光功率
-curl "http://localhost:8000/api/devices/1/optical-power" \
-  -H "Authorization: Bearer <token>"
-
-# 3. 查看后端日志
-docker compose logs backend | grep IMCService
-
-# 4. 直接测试 iMC API（验证认证是否工作）
-curl -k -v "https://172.16.1.252:8443/imcrs/epon/onu/onuLightWaneInfo?mac=1484-7790-4840"
-```
-
-### 测试响应示例
-
-**重启成功：**
-```json
-{"success": true, "message": "设备正在重启，请稍后..."}
-```
-
-**重启失败（ONU不存在）：**
-```json
-{"success": false, "message": "重启失败: ONU不存在"}
-```
-
-**光功率获取成功：**
-```json
