refactor: standardize event file actions and apply batch formatting

- Updated 'create_event_file_obj_from_hosted_file_async' to use the modern V3 action endpoint.
- Standardized 'prevent_default' helper names in root Event and Archive components.
- Applied batch formatting (printWidth: 80) across the settings and events modules.
