This commit addresses several bugs related to the mounting, unmounting, and deletion of encrypted backups, as well as a crash when listing backups.
The key changes are:
- **Fix Double Mount on View:** Removed redundant mount operation when viewing encrypted backup contents. The mount is now handled by a single, centralized function.
- **Fix Deletion of Encrypted Backups:**
- The container is no longer re-mounted if already open, preventing a second password prompt.
- Deletion of encrypted *user* backups is now performed with user-level permissions, removing the need for a third password prompt via pkexec.
- **Fix UI Refresh after Deletion:** The backup list now correctly refreshes after a backup is deleted.
- **Fix Crash on Empty Backup List:** Resolved an `UnboundLocalError` that occurred when listing backups from an empty or non-existent backup directory.
- **Improve Mount Detection:** The `is_mounted` check is now more robust to prevent race conditions or other OS-level inconsistencies.
