feat(Q24+Q26): balance threshold + SP auto-deploy worker

Q24: Magic wallet entry/exit trigger now uses Balance <= 1,000,000 Rials
  instead of Balance == 0 (products have varying prices so exact zero
  is unreachable). Added MagicWalletEntryThreshold to SystemConstants.

Q26: StoredProcedureDeploymentService (IHostedService) auto-deploys
  stored procedures on startup via embedded SQL resources + SHA256
  checksum comparison. Creates [CMS].[__StoredProcedureVersions] table
  automatically. Supports GO batch separators.
