feat(webui): replace TUI with full web UI + local openbox desktop

- Remove audit/internal/tui/ (~3000 LOC, bubbletea/lipgloss/reanimator deps)
- Add /api/* REST+SSE endpoints: audit, SAT (nvidia/memory/storage/cpu),
  services, network, export, tools, live metrics stream
- Add async job manager with SSE streaming for long-running operations
- 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
- Update .profile, bee.sh, and bible-local docs
