feat: 版本详情完整功能 + 数据串联 + 登录模块

- 版本详情：关联需求Tab（从需求池添加已采纳需求/移除释放）
- 版本详情：调研/产品方案/UI设计Tab（计划CRUD、完成提交成果、耗时统计）
- 版本详情：超期校验（结束日期超版本截止需填写原因）
- 版本详情：概览统计卡片（加班时长/排名/原因占比）
- 数据串联：产品→项目→版本→需求→加班全链路贯通
- 版本管理：规划中版本可删除，删除释放关联需求
- 数据清理：仅保留翻台宝/值班，需求池10条值班待评审需求
- 修复：列表页overflow裁剪菜单问题（4个页面统一修复）
- 新增：登录模块、AuthGuard、VersionPlan store
