feat(project): Complete Project Lifecycle capability with full TDD workflow

- Implement ProjectController with CRUD, status transitions, estimate/forecast
- Add ProjectService with state machine validation
- Extract ProjectStatusService for reusable state machine logic
- Add ProjectPolicy for role-based authorization
- Create ProjectSeeder with test data
- Implement frontend project management UI with modal forms
- Add projectService API client
- Complete all 9 incomplete unit tests (ProjectModelTest, ProjectForecastTest, ProjectPolicyTest)
- Fix E2E test timing issues with loading state waits
- Add Scribe API documentation annotations
- Improve forecasted effort validation messages with detailed feedback

Test Results:
- Backend: 49 passed (182 assertions)
- Frontend Unit: 32 passed
- E2E: 134 passed (Chromium + Firefox)

Phase 3 Refactor:
- Extract ProjectStatusService for state machine
- Optimize project list query with status joins
- Improve forecasted effort validation messages

Phase 4 Document:
- Add Scribe annotations to ProjectController
- Generate API documentation
