Remove legacy indexed disk metrics parsing

Browse Source 
Eliminate duplicate storage entries by removing old disk_count dependency.
Dashboard now uses pure auto-discovery of disk_{pool}_usage_percent metrics.
Fixes multiple storage instances (Storage 0, Storage 1, Storage root)
showing only proper tree structure format.
