hotfix: enhance radio button and file upload components

- Improved the styling and functionality of the radio button component, including a new radio button style.
- Added a loading spinner to the file upload component to indicate when large files are being processed.
- Added the ability to sort files in the file upload component.
- Fixed an issue where the radio button component was not correctly updating the model value.
- Updated the dataset creation and edit forms to use the new radio button component.
- Added a global declaration for the `sort_order` property on the `File` interface.
- Updated the API to filter authors by first and last name.
- Removed the import of `_checkbox-radio-switch.css` as the radio button styling is now handled within the component.
