persistence This commit introduces a major architectural change by replacing the previous hardcoded user and data system with a robust, database-driven approach. It lays the foundation for persistent data storage for all application models. Key Changes: - **Database Integration:** - Added `GORM` and `SQLite` for the database layer. - The database is now initialized and migrated on application startup. - Configuration is managed through environment variables (`DATABASE`, `USERS_FILE`). - **User Authentication & Management:** - The login endpoint (`/api/token`) now authenticates users against the database. - JWT claims are now populated with real user data (`id`, `username`, `is_superuser`). - Implemented a system to seed the database with initial users from a `users.json` file. - **New User API Endpoints:** - `GET /api/users`: Retrieves a list of all users (superuser access required). - `GET /api/users/user`: Fetches the data for the currently authenticated user based on their JWT. - **Data Model Overhaul:** - Refactored all data models (`User`, `Category`, `Operation`, `Subcategory`) to include GORM tags, relationships, and a `BaseModel` with auto-generated UUIDs for primary keys. - Separated user-related structs into `User` (database model), `AuthRequest` (login payload), and `UserResponse` (safe API response). - **Middleware & Routing:** - Improved JWT error handling for clearer client-side messages. - Added a new middleware to allow passing the JWT in the request body for more flexible client integration.
