feat: 完整功能迭代 — 移动端+PC端全面优化

新增:
- 今日纪要 (6分类+彩色标签+时间选择器)
- 客户经理PC端工作台 (我的数据,5模块CRUD)
- 用户管理页 (支局长修改角色)
- 客户备注/收支费用(金额+单位)/联系人管理
- 拜访人姓名+电话字段
- 客户导入导出/旧周报导入模板下载
- 序号列+分页(25/50/100)

修复/优化:
- Hash路由→HTML5 History, Casdoor回调正常
- 时区统一为Asia/Shanghai (today_cst)
- 数据库懒加载→selectinload预加载
- 日期解析兼容ISO datetime字符串
- 文件上传定位修复 (position:relative)
- 表单button type='button'防止误提交
- 分管领导权限(只读客户档案,不可编辑)
- 侧边栏折叠+SVG图标
- 拜访方式/紧急度统一chip风格
- 时间范围统一为el-time-picker(is-range)
- 全局CSS设计变量+box-sizing修复滚动条
