refactor: rename UserWalletChangeLog→UserWalletHistory, add History interceptor & migration

- Rename UserWalletChangeLog to UserWalletHistory across 54+ files (entities, configs, DTOs, commands, queries, protos, services)
- Rename 34 files and 11 directories accordingly
- Rename proto file userwalletchangelog.proto → userwallethistory.proto
- Add IHasHistory<T> generic interface for history auto-tracking
- Implement IHasHistory<PackageHistory> on Package entity
- Add HistoryTrackingSaveChangesInterceptor (reflection-based, auto-fills Old* values from OriginalValues)
- Wire interceptor in DI and ApplicationDbContext
- Add EF migration Q27_HistoryTables_And_RenameWalletHistory:
  * RenameTable UserWalletChangeLogs → UserWalletHistories (preserves data)
  * Rename PK, FK constraints and indexes via sp_rename
  * CreateTable ClubMembershipCycleHistories + PackageHistories
