Features: 1) Add configurable options for BACKUP_DATABASE and BACKUP_MEDIA in system settings; 2) Enhance backup_task to handle selective backups and return status message;

Fixes: 1) Add exception handling for invalid image file dimensions in `validators.py`;

Extra: 1) Update settings categories to include new system options; 2) Improve code clarity in `backup_task` and `validators.py`.
