feat: Enhance logging and add chart endpoints

- Updated LoggerDB to remove all active sinks on initialization.
- Added a new PostgresCredencial setup in notas_mmr.py for database connection.
- Replaced print statements with logger calls for better logging in notas_mmr.py.
- Introduced new FastAPI endpoints for various chart types (bar, line, pie, scatter).
- Created Editor_biblioteca.css for styling the rich text editor.
- Implemented Editor_Test.tsx to test the rich text editor functionality.
