test(project): Add Phase 1 pending tests for Project Lifecycle

Capability 3: Project Lifecycle Management - Phase 1 (RED)

E2E Tests (12 test.fixme):
- Create project with unique code
- Reject duplicate project code
- Valid/invalid status transitions
- Estimate approved requires estimate > 0
- Workflow progression
- Estimate rework path
- Project on hold
- Cancelled project
- Set approved estimate
- Update forecasted effort
- Validate forecasted effort

API Tests (9 markTestIncomplete):
- POST /api/projects
- Project code uniqueness
- Status transition validation
- Estimate/forecast endpoints

Unit Tests (3 markTestIncomplete):
- Project status state machine
- ProjectPolicy authorization
- Forecasted effort validation

All 173 tests passing (31 backend, 32 frontend, 110 E2E)
