feat(bp): repositories + identity generation for runtime-inserted tables

Add ValueGeneratedOnAdd to ViewerBattlePassProgress.Id and ViewerBattlePassClaims.Id so Postgres generates IDENTITY values at runtime. Regenerate AddBattlePass migration in-place to include the IdentityByDefaultColumn annotations. Add IBattlePassRepository / BattlePassRepository (season lookup + level-curve cache) and IViewerBattlePassRepository / ViewerBattlePassRepository (get-or-create progress, claim reads/writes).
