Implement people management features by adding API endpoints for retrieving school rosters and individual person cards. Enhance the UI to support a people browser with filtering and pagination capabilities. Update localization strings for improved user experience and ensure robust handling of person data. Revise documentation to reflect new API functionalities and update tests to validate the new features.
