chore: remove redundant sensors card and bump version to 1.22.1

- Disable sensors data collection (CPU temp already shown in CPU card)
- Remove unused sensor-related functions (collectSensors, prettifyLabel, hasSensorData, renderSensorsCard)
- Remove unused gopsutil/sensors import
- Fix inline spinner disown call with explicit PID
- Update version from 1.22.0 to 1.22.1
- Update SECURITY_AUDIT.md to match new version and date
