Update version to 0.1.22 and fix system metric status calculation

- Fix /tmp usage status to use proper thresholds instead of hardcoded Ok status
- Fix wear level status to use configurable thresholds instead of hardcoded values
- Add dedicated tmp_status field to SystemWidget for proper /tmp status display
- Remove host-level hourglass icon during service operations
- Implement immediate service status updates after start/stop/restart commands
- Remove active users display and collection from NixOS section
- Fix immediate host status aggregation transmission to dashboard
