Move Disk Space Analyzer to Performance Analysis menu

The Disk Space Analyzer is a performance/system health tool, not a
backup tool. Moving it to the Performance Analysis menu makes more
logical sense for users looking for system diagnostics.

Changes:
- Removed from Backup & Recovery → Maintenance section (was option 4)
- Added to Performance Analysis → System Health section (option 6)
- Updated both show_performance_menu() and handle_performance_menu()
- Removed from show_backup_menu() and handle_backup_menu()

New Location:
Main Menu → 4) Performance Analysis → 6) Disk Space Analyzer

This groups it with other system health tools like:
- Loadwatch Health Analyzer
- Hardware Health Check
- Network & Bandwidth analysis
