Add Stadium Progress system and themed loading spinners

Stadium Progress & Achievements:
- Add StadiumVisit and Achievement SwiftData models
- Create Progress tab with interactive map view
- Implement photo-based visit import with GPS/date matching
- Add achievement badges (count-based, regional, journey)
- Create shareable progress cards for social media
- Add canonical data infrastructure (stadium identities, team aliases)
- Implement score resolution from free APIs (MLB, NBA, NHL stats)

UI Improvements:
- Add ThemedSpinner and ThemedSpinnerCompact components
- Replace all ProgressView() with themed spinners throughout app
- Fix sport selection state not persisting when navigating away

Bug Fixes:
- Fix Coast to Coast trips showing only 1 city (validation issue)
- Fix stadium progress showing 0/0 (filtering issue)
- Remove "Stadium Quest" title from progress view
