feat(loyalty): wallet debug page, Google Wallet fixes, and module config env_file standardization

- Add wallet diagnostics page at /admin/loyalty/wallet-debug (super admin only)
  with explorer-sidebar pattern: config validation, class status, card inspector,
  save URL tester, recent enrollments, and Apple Wallet status panels
- Fix Google Wallet fat JWT: include both loyaltyClasses and loyaltyObjects in
  payload, use UNDER_REVIEW instead of DRAFT for class reviewStatus
- Fix StorefrontProgramResponse schema: accept google_class_id values while
  keeping exclude=True (was rejecting non-None values)
- Standardize all module configs to read from .env file directly
  (env_file=".env", extra="ignore") matching core Settings pattern
- Add MOD-026 architecture rule enforcing env_file in module configs
- Add SVC-005 noqa support in architecture validator
- Add test files for dev_tools domain_health and isolation_audit services
- Add google_wallet_status.py script for querying Google Wallet API
- Use table_wrapper macro in wallet-debug.html (FE-005 compliance)
