Implement toggle for read/write mode across entity pages and enhance Documents and Divers functionality

- Added a toggle for switching between read and write modes on the Articles, Documents, Journaux, Tiers, and Divers pages, allowing users to access both data retrieval and data submission endpoints.
- Updated the Documents page to cover all 9 documented endpoints, including 7 for reading and 2 for writing, with appropriate error handling.
- Created a new Divers page to handle three endpoints: getserialnumber, codes_list, and custom_geninv_updatestock (the latter being non-functional).
- Introduced new methods in LogisticsService for handling PDF generation and stock updates, with corresponding updates in the API documentation.
- Improved form field components for better visual spacing in input fields.
