HEL-222: 整合自动提醒引擎(212b1f9)到现行测试版 d6f39e0

- 迁移链追加 0009_reminders_engine：旧 manual reminders 表改名
  reminders_legacy_manual 保留历史，新建 reminders/reminder_events/
  reminder_settings（append-only 触发器）
- server.py：新提醒 API（pending/scan/send/manual/resend/settings/
  公司端收件与状态流转）替换旧 manual-send 端点
- web：admin 待提醒清单+扫描+详情抽屉，公司端通知动态化+
  去处理事件委托；设置保存同步提醒扫描参数
- 移除被取代的 settings.pending_items/send_reminders 与旧 UI 逻辑
- 全量测试 346 项通过（5 项浏览器跳过与历史一致）

+
+1. [项目需求](项目需求.md)：先知道系统要解决什么问题，以及哪些规则绝不能碰。
+2. [最新进度](最新进度.md)：再确认哪些能力已经真实完成，哪些仍未完成。
+3. [任务清单](任务清单.md)：最后挑选下一项工作，避免重复做已经完成的事。
+4. 需要技术细节时，再查看 `decisions/` 中的技术决定和 `issues/` 中保留的历史任务规格。

+- 新功能改变产品规则时，同时更新 `项目需求.md`；技术方案有变化时，补充 `decisions/` 的决定记录。
+- 写进手册的“已完成”必须能在代码、测试或已合并提交中找到依据；只有计划、页面演示或口头讨论的内容，一律写为“未完成”。
+- 不删除历史文档。旧内容与当前代码不一致时，在旧文件开头加“已过时，仅留档备查”提示，并在本目录写新版说明。

+- 支持中信、农行、工行、建行、河南农商行、郑州银行六类样本的 `.xls` / `.xlsx` 流水解析；能识别变动的表头位置和列顺序，并校验余额连续性。

+- 已实现管理员与公司用户登录、首次改密、会话失效、登录失败限流、服务端权限隔离和审计记录。
+- 已实现公司、用户、银行账户、别名等主数据管理；公司提交的银行账户需管理员审核后才能参与上传和识别。

+- 已实现规范转账事件和双边流水匹配。匹配决定保留历史，无法自动判断的记录进入人工审核；同公司调拨、外部流水和未锁定的单边记录不进入已确认的公司间往来。
+- 已有登录页、总账端和公司端页面，最近一次合并完成了登录页视觉改版。

+# 项目需求
+
+## 这个系统做什么
+
+这是河南金牛实业集团有限公司内部各公司之间的资金往来管理系统。它把各公司的银行流水集中起来，识别同一笔公司间转账的两边记录，形成可以一路查回原始银行流水的往来结果。
+
+系统有两个独立入口：
+
+- 总账管理端：管理公司、公司账号、银行账户、导入记录、异常和公司间转账匹配。
+- 公司出纳端：只处理本公司的账户登记、流水上传、工作表确认和本公司相关异常。
+
+## 必须做到的业务规则
+
+- 银行原始文件和原始流水是证据，导入后不能直接修改或删除；修正必须通过可追溯的审核决定、冲销或调整完成。
+- 一笔公司间转账的收、付两边只能算作一个经济事件，不能因为有两条银行流水就重复计算。
+- 同一家公司不同银行账户之间调拨，不计入公司间往来。
+- 账号、金额、方向、日期和余额等可核对信息优先于户名；信息不完整或有歧义时进入异常审核，不能猜。
+- 已确认金额和待确认金额必须分开；所有余额都要说明统计截止日期和未决金额。
+- 公司用户只能查看、上传和导出本公司的数据。这个限制由服务端执行，页面上“看不见”不等于有权限限制。
+- 起算日前的流水必须保留，但不参与期内计算；期初余额、流水覆盖断档、无业务校准、月结和调整都要留痕。
+
+## 当前技术边界
+
+项目使用 Python 标准库服务、SQLite 数据库和浏览器页面。银行模板支持 `.xls` 与 `.xlsx`，按表头识别而非依赖固定行列。金额使用精确十进制，真实运行数据放在 `data/`，不进入代码仓库。
+
+系统目前仍是测试环境项目，不能当作已完成生产部署：正式上线前仍需补齐核算、期初与断档、月结、备份、监控和 HTTPS 等能力。
