Implement CRUD functionality for Articles and Tiers with enhanced API documentation

- Introduced new endpoints for creating and modifying articles (`art_add`, `art_mod`) and tiers (`third_add`, `third_mod`), allowing users to manage these entities effectively.
- Updated the Articles and Tiers pages to include forms for adding and modifying records, complete with parameter tables for clear guidance on required inputs.
- Enhanced the API documentation to include detailed descriptions, examples, and metadata for the new endpoints, improving usability and understanding for developers.
- Created a new rule for writing conventions with French accents to ensure consistency across the project.
- Updated existing documentation to reflect structural changes and added a summary table for CRUD operations.
- Added tests to verify the functionality of the new features and ensure robust error handling.
