feat: Integrate rclone command functionality into configuration management

- Added support for selecting rclone commands and their associated flags in the configuration form.
- Implemented backend logic to handle rclone command retrieval and flag management.
- Enhanced the database schema to include rclone command and flag fields in the transfer configuration.
- Created new migration scripts to add rclone-related tables and fields.
- Updated the scheduler to execute transfers using the selected rclone command and flags.
- Developed new handlers for rendering rclone command options and flags in the web interface.
- Improved error handling and logging for rclone command execution and configuration updates.
