test(frontend): UIUX E2E 测试 — 新增路由导航/创始人端/Admin端/工作台/移动端适配

新增 6 个 E2E 测试文件，覆盖 2-task-uiux.md 全部 50 项任务：
- uiux-navigation.spec.ts: 8 tests (today/compare/threads/workspace/ooda/ai-plus/profiles)
- sidebar-navigation.spec.ts: 6 tests (投资人 Sidebar 6 业务域)
- founder-uiux.spec.ts: 7 tests (创始人端 6 域导航)
- admin-uiux.spec.ts: 3 tests (Admin 6 管理域 + 商业秘密保护)
- workbench-uiux.spec.ts: 5 tests (Highlights/WorkMode/Tab/InsightRail)
- mobile-uiux.spec.ts: 5 tests (移动端抽屉导航 + 创始人底部导航)

同时修复全部 no-explicit-any 警告，替换为 TypeScript 接口定义。

测试结果: 41 E2E passed, 405 backend passed
