Implement comprehensive partnership tracking system and tournament
management features including round-robin, single/double elimination,
and Swiss system pairings.
Changes:
- Add partnership_games and partnership_stats tables
- Implement PartnershipTracker service for recording partnership data
- Add tournament generator with multiple formats
- Create tournament management actions and views
- Add acceptance tests for partnership tracking
- Fix PartnershipTracker to use single snapshot per player per match

Note: All 8 acceptance tests now passing
The Elo calculator was incorrectly rejecting valid scores (10-7) because
it checked if team score >= 10 without verifying the opposing team's score.
Changes:
- Update winner determination to check both score >= 10 AND score > opponent
- Add detailed error message with actual scores for debugging
- Ensure only one team can win (not both reaching 10 points)
- Implement EloCalculator service for 2v2 Euchre matches
- Create background job processing with GoodJob
- Add single match entry form
- Add CSV upload for batch match entry
- Create player rankings view
- Add database schema for matches and elo snapshots
