* fix(nginx-ui): remove admin user hack, use setup wizard instead
The previous install script started nginx-ui for 3 seconds, stopped it,
and ran reset-password to create an admin user. This caused:
- Race condition: the internal setup wizard could trigger during the brief
start window, conflicting with the reset-password approach
- Admin users unable to login after the setup wizard fired
- Settings lockup due to overloaded app.ini with hardcoded nginx paths
that conflict with UI-managed settings
Changes:
- Remove start/stop/reset-password hack from install script
- Simplify app.ini to match upstream defaults (minimal config)
- Let users complete the natural setup wizard on first visit
- Update JSON: remove default credentials, add setup wizard note
- Add setup wizard hint to CT script output
The setup wizard properly handles admin account creation and ACME email
configuration, which are both needed for full functionality.
