Phase 5: Per-package commission + golden ref cleanup

- Fix golden/طلایی string refs in user-facing messages (ActivateClubMembership)
- Rename HasPurchasedGoldenPackage → HasPurchasedPackage (DTO, Handler, Proto, Mapping)
- ORM commission: per-user-package calculation via ClubMembership.LastPackageId
  - Build userPackageMap, per-user maxBalancesPerLeg/maxNetworkLevel
  - Carryover keyed by (UserId, PackageId) tuple
- SP commission: loop over packages, pass @PackageId/@InputMaxBalancesPerLeg/@InputMaxNetworkLevel
- sp_CalculateWeeklyBalances: accept 3 new params, filter by PackageId, insert PackageId column
