Clarify local vs cloud storage in agent status

Changed "Storage Status" to "Local Storage Status" to clearly indicate
this shows agent data (130M cache/logs/config), not backup storage.

Added note directing users to Acronis web console for actual backup
storage usage (19GB cloud storage shown there).

Prevents confusion between:
- Local agent data: 130M (what script shows)
- Cloud backup storage: 19GB (shown in web interface)
