feat(m13): cross-resource search + dashboard completion, tests, e2e

- SearchService (cross-resource keyword search across board/chat/todo/file/
  event/meeting/milestone/note with type filter, project isolation)
- DashboardService (project dashboard: in-progress todos, near-due(7d),
  latest chat/board/notes/files(5), next meeting, milestones w/ progress,
  recent activity(10); personal dashboard: my projects, incomplete todos,
  upcoming meetings, unread notifications, overdue tasks, recent activity)
- CalendarRepository.findByProject
- APIs: GET /api/projects/:projectId/search, GET /api/dashboard
- Screens: complete personal dashboard, complete project overview,
  search page + SearchForm, ProjectNav 検索 link
- Unit tests (SearchService, DashboardService) + e2e dashboard
