  services, network, export, tools, live metrics stream

- Add platform.SampleLiveMetrics() for live fan/temp/power/GPU polling
- Add multi-page web UI (vanilla JS): Dashboard, Metrics charts, Tests,
  Burn-in, Network, Services, Export, Tools
- Add bee-desktop.service: openbox + Xorg + Chromium opening http://localhost/
- Add openbox/tint2/xorg/xinit/xterm/chromium to ISO package list
