Adds a Tools/Utilities tab to the web interface with one-click
maintenance buttons that previously required SSH:
- Git status panel (branch, dirty state, recent commits)
- Pull latest (rebase) and force reset to origin/main
- Reinstall base requirements (pip, with output)
- Reinstall per-plugin requirements (pass/fail per plugin)
- Clear __pycache__ directories
- Quick-access restart for display and web services
Also exposes the hzeller row_address_type option (0–4) in the
Display settings tab. The backend already read this value from
config; the UI, API field list, and validation were missing.
