Implement person name retrieval by token and enhance mention handling

- Added a new function to retrieve a person's name from the database using their token, addressing issues with damaged mentions that display tokens instead of names.
- Updated the content parsing logic to ensure that mentions include both data-id and data-label attributes, improving the display of names in the user interface.
- Enhanced the handling of inner text to correctly replace tokens with real names when applicable, ensuring a more seamless user experience.
