This change improves the layout of the Read the Docs documentation by creating a dedicated API reference page.
Key changes:
- Created a new `docs/api.rst` file to contain all C++ API documentation generated from Doxygen.
- Added references to both `MedicalLib/MedicalLib.h` and `MedicalLib/Patient.h` in `api.rst`.
- Updated `docs/index.rst` to remove the inline API documentation and include a link to the new `api.rst` page in the `toctree`.
This results in a cleaner, more organized, and complete documentation site.
