Implement comprehensive dashboard improvements and maintenance mode

Browse Source 
- Storage widget: Restructure with Name/Temp/Wear/Usage columns, SMART details as descriptions
- Host navigation: Only cycle through connected hosts, no disconnected hosts
- Auto-discovery: Skip config files, use predefined CMTEC host list
- Maintenance mode: Suppress notifications during backup via /tmp/cm-maintenance file
- CPU thresholds: Update to warning ≥9.0, critical ≥10.0 for production use
- Agent-dashboard separation: Agent provides descriptions, dashboard displays only
