feat(后端): 添加授权体系、系统监控与试用期计提

按 2026-11-02 需求补齐计划交付后端能力：
- 角色授权：权限目录化，接口统一准入校验，未登记默认拒绝；
  管理员判断改为按数据库角色重新判定，防止权限码持有者绕过
- 系统监控：单进程采集资源、请求与异常指标，分钟级聚合，
  阈值配置化；敏感配置增加 repr 保护，Redis 密码 URL 转义
- 试用期计提：按回款日判定并写入快照，年度结清与调整单联动；
  人员模型补试用期、离职日期与工资版本历史字段
- 计提模板：公式骨架受控，页面维护名称与参数绑定
- T+ 采集：自动化配置表与进度查询

内置角色禁停用保护对齐模块注释；核算规则版本提为常量并
补充批量核算失败堆栈日志。

影响范围：后端全部模块、数据库迁移 V22-V28
验证：uv run ruff check 通过；922 个单元测试全部通过；
集成测试因本机 MySQL 数据卷被其他容器锁定暂未运行
