feat: Tier2 backup pauses when destination drive is inactive (Inaktív)

Deactivated drives (Schedulable=false) now treated like disconnected for
Tier2 backups. New IsStoragePathSchedulable() checks active+connected+not
decommissioned. UI shows yellow "Cél meghajtó inaktív" badge, scheduler
skips silently with WARN log.
