feat: implement Egg Quick Capture form (Step 7.3)

Add the Egg Quick Capture functionality at GET / with POST /actions/product-collected.

Changes:
- Add list_active() to LocationRepository for active locations only
- Create web/templates/eggs.py with MonsterUI form components
- Create web/routes/eggs.py with GET and POST handlers
- Add CSRF bypass in dev_mode for easier development/testing
- Resolve ducks at location server-side for egg collection
- UX: location sticks after submit, quantity clears

Tests: 9 new tests covering form rendering and submission
