- Implemented `google_drive_callback.html` for processing Google Drive authorization, including UI for success and error states. - Added JavaScript functionality for exchanging authorization codes, saving settings, and handling folder selection. - Created `google_drive_callback_error.html` to display error messages during the authorization process.
