- Updated multiple DTO classes across various modules to replace the `Config` class with `model_config = ConfigDict(from_attributes=True)`.
- This change enhances consistency in attribute handling and aligns with the latest Pydantic practices.
- Adjusted error handling in core modules to change status codes from `HTTP_422_UNPROCESSABLE_ENTITY` to `HTTP_422_UNPROCESSABLE_CONTENT` for improved clarity in validation responses.
- Added schemas, services, and routers for PROSEC, RCG2, Regulaciones, REIT, RequisitoPrevio, TLCS, and Vehiculos modules.
- Each module includes search and get by ID functionalities.
- Integrated FastAPI routers for each module into the main SITAR router.
- Ensured proper response models using Pydantic for data validation.
