Add user and employee management enhancements with database schema updates

- Introduced new columns `status`, `created_by`, and `updated_by` in the `users` table to track user status and ownership.
- Updated the `employees` table to include a foreign key reference to the `users` table via `user_id`.
- Created migration script `0012_users_primary.sql` to apply these changes to the database schema.
- Enhanced the `EmployeesService` and `EmployeesRepository` to support user assignments and related data retrieval.
- Updated DTOs and service methods to reflect the new user and employee relationships.
- Added unit tests to validate the new functionality and ensure data integrity.
- Modified existing controllers to accommodate the new fields and relationships in user and employee management.
