- Enhanced UserTable component to include additional user fields (first name, last name, email, admin status) and updated input handling.
- Modified fetcher utility to use new user data API endpoint.
- Adjusted login functionality to point to the new admin login endpoint and handle unauthorized access.
- Refactored user actions utility to align with updated API endpoints for user management.
- Updated backend routes for user and loan data management to reflect new structure and naming conventions.
- Revised SQL schema and mock data to accommodate new fields and constraints.
- Changed Docker configuration to use the new database name.
