Hide backup panel when no backup data is present

Browse Source 
- Add has_data() method to BackupWidget to check if backup metrics exist
- Modify dashboard layout to conditionally show backup panel only when data exists
- When no backup data: system panel takes full left side height
- When backup data exists: system and backup panels share left side equally

Prevents empty backup panel from taking up screen space unnecessarily.
