The captured shape ({"1":[], "3":[], "4":[]}) is the empty-period
wire echo; the client parser (LoadDetail.cs:553) only reads normal/total/
campaign. Table, entity, seed, and importer were never wired to a code path.
Replaced by config-section catalog + service in the follow-up commits.
- IndexResponse.BattlePassLevelInfo widened to IReadOnlyDictionary<string,BattlePassLevel>?
so any IReadOnlyDictionary impl (FrozenDictionary, wrapper, etc.) serializes correctly
instead of silently null-ing via a failed as-cast
- LoadController.Index now takes CancellationToken ct and threads it to GetLevelCurveAsync
instead of CancellationToken.None
- BattlePassRepository.ResetLevelCurveCache changed from public to internal; added
InternalsVisibleTo("SVSim.UnitTests") to SVSim.Database.csproj (was absent)
