Redesign dashboard: split Runtime Health and Hardware Summary

- Runtime Health now shows only LiveCD system status (services, tools,
  drivers, network, CUDA/ROCm) — hardware component rows removed
- Hardware Summary now shows server components with readable descriptions
  (model, count×size) and component-status.json health badges
- Add Network Adapters row to Hardware Summary
- SFP module static info (vendor, PN, SN, connector, type, wavelength)
  now collected via ethtool -m regardless of carrier state
- PSU statuses from IPMI audit written to component-status.json so PSU
  badge shows actual status after first audit instead of UNKNOWN
