fix: resolve specificStadium achievement ID mismatch

The Green Monster (Fenway) and Ivy League (Wrigley) achievements
weren't working because:
1. Symbolic IDs use lowercase sport (stadium_mlb_bos)
2. Sport enum uses uppercase raw values (MLB)
3. Visits store stadium UUIDs, not symbolic IDs

Added resolveSymbolicStadiumId() helper that:
- Uppercases the sport string before Sport(rawValue:)
- Looks up team by abbreviation and sport
- Returns the team's stadiumId as UUID string

Also fixed:
- getStadiumIdsForLeague returns UUID strings (not symbolic IDs)
- AchievementProgress.isEarned computed from progress OR stored record
- getStadiumIdsForDivision queries CanonicalTeam properly
