feat: 三项联动 — 计划过期提醒 + 拜访自动关闭 + 批量制定

1. 计划过期自动提醒:
   - scheduler.py 新增 check_overdue_plans()
   - 每日 9:00 检查过期计划(plan_date < today, status=计划中)
   - 按经理汇总 → 企微推送提醒消息

2. 拜访后自动关闭计划:
   - create_visit 后自动将匹配的计划标记为「已完成」
   - 条件: customer_id 匹配 + status=计划中 + plan_date <= visit_date

3. 亮灯表批量制定:
   - 红灯/黄灯卡片右上角 ☐ 复选框
   - 勾选后出现「批量制定计划」按钮
   - 弹窗统一设置日期+内容 → 批量 POST
