Backend: - Add source/used_by/available/error fields to diskUsage in system status - collectDiskUsage() now reads /proc/mounts, samba shares and NFS exports from DB - Paths are deduplicated; shared paths list all shares/exports using them - syscall.Statfs errors surface as available=false with user-facing error - collectServiceStatus made a method of Server (receiver consistency) Frontend: - Settings page now shows two cards: mount points and shared resources - Each path shows source badge (Sistema/Mount/SMB/NFS), used_by chips, progress bar - Unavailable paths show amber warning instead of progress bar - DiskUsage interface updated with new fields - NFSExport interface updated with structured fields (fsid, async, etc) - NFS page updated to use new export fields
