Complete FrontOffice BFF to CMS Migration

- Migrated all 9 services from FrontOffice.BFF to CMS architecture
- Enhanced user.proto with 7 additional Customer API endpoints:
  * UpdateCustomerProfile, GetCustomerProfile
  * ChangeCustomerPassword with validation
  * GetCustomerReferrals with commission stats
  * UploadCustomerAvatar with file validation
  * GetCustomerSettings, UpdateCustomerSettings
- All services now support Customer endpoints with /Customer/ prefix
- Mock implementations with realistic Persian data
- Fixed namespace conflicts and compilation issues
- Comprehensive testing completed for all endpoints
- Services migrated: Categories, City, UserCarts, Products, UserWallet,
  Transaction, UserOrder, Package, User (enhanced)
