- Modified UserAccount, UserCredential, UserVerification, City, StateProvince, and Country entities to use 'RowVersion' instead of 'Timer'.
- Updated tests and command handlers to reflect changes in concurrency token from 'Timer' to 'RowVersion'.
- Adjusted BreweryDto and BreweryDtoMapper to include 'RowVersion' and updated mapping logic accordingly.
- Ensured all repository methods and interfaces are aligned with the new concurrency handling approach.
