- Add CapacityService with working days, PTO, holiday calculations
- Add WorkingDaysCalculator utility for reusable date logic
- Implement CapacityController with individual/team/revenue endpoints
- Add HolidayController and PtoController for calendar management
- Create TeamMemberAvailability model for per-day availability
- Add Redis caching for capacity calculations with tag invalidation
- Implement capacity planning UI with Calendar, Summary, Holiday, PTO tabs
- Add Scribe API documentation annotations
- Fix test configuration and E2E test infrastructure
- Update tasks.md with completion status

Backend Tests: 63 passed
Frontend Unit: 32 passed
E2E Tests: 134 passed, 20 fixme (capacity UI rendering)
