Adds the four onboarding pieces that were missing:
- flywithlua_present Tauri command + wizard step that checks the plugin and
links the FlyWithLua NG+ download when it's absent.
- Wizard step explaining how to enable X-Plane's Web/REST API (Settings>Network).
- FlyWithLua-Sync status row in the live diagnostics, from /api/health.lua
('N Skripte aktiv' / 'FlyWithLua fehlt' / 'kein X-Plane').
- 4-step guided wizard (X-Plane folder → FlyWithLua → Web-API → install+start)
that auto-opens on first launch and is reachable via the header Einrichten
button; the final step hands off to the normal server start (auto-installs Lua).
Verified the wizard DOM flow + the dLua status against a live bridge.
