(1) RegisterAnonymousViewer now catches the unique-violation
race (SQLSTATE 23505 on Postgres / code 19 on SQLite) and
re-reads by UDID, returning the existing row instead of
surfacing 500 to the second concurrent /tool/signup caller.
New repo test exercises the back-to-back register path.
(2) Add unique index on SocialAccountConnection (AccountType,
AccountId). The auth handler's find-or-link path claimed
this index existed as the dedup backstop; the claim was
accurate as design intent but the schema was missing. Now
matched. Comment in handler updated.

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).
