Refactor user domain to utilize string IDs and integrate MongoDB ORM

- Updated User entity to embed MongoDB model and replace uuid.UUID with string for ID fields.
- Modified repository methods to accept string IDs instead of uuid.UUID, enhancing compatibility with MongoDB.
- Refactored service and handler methods to align with the new ID type, ensuring consistent usage across the user management functionality.
- Improved response handling in UserListResponse to directly use string IDs.
- Streamlined index creation in the user repository using the MongoDB ORM for better maintainability.
