feat(tui): rebuild TUI around hardware diagnostics (Health Check + two-column layout)

- Replace 12-item flat menu with 4-item main menu: Health Check, Export support bundle, Settings, Exit
- Add Health Check screen (Lenovo-style): per-component checkboxes (GPU/MEM/DISK/CPU), Quick/Standard/Express modes, Run All, letter hotkeys G/M/S/C/R/A/1/2/3
- Add two-column main screen: left = menu, right = hardware panel with colored PASS/FAIL/CANCEL/N/A status per component; Tab/→ switches focus, Enter opens component detail
- Add app.LoadHardwarePanel() + ComponentDetailResult() reading audit JSON and SAT summary.txt files
- Move Network/Services/audit actions into Settings submenu
- Export: support bundle only (remove separate audit JSON export)
- Delete screen_acceptance.go; add screen_health_check.go, screen_settings.go, app/panel.go
- Add BMC + CPU stress-ng tests to backlog
- Update bible submodule
- Rewrite tui_test.go for new screen/action structure
