feat(desktop-onboarding): neue Onboarding-UI implementiert, Backup- und Rollenmanagement hinzugefügt

- Einbindung eines komplett überarbeiteten Onboarding-Screens mit validierten Eingaben für Gerätename, Sicherheitsschlüssel und Backup-Pfad.
- `SettingsManager` eingeführt zur Speicherung der Onboarding-Daten in `settings.json`.
- Navigation verbessert: Onboarding-Workflow startet, wenn Konfiguration fehlt; neues "Setup"-Icon in der Navigationsleiste hinzugefügt.
- Backend: Geräte-API und `DeviceSecurityFilter` für Authentifizierung per Sicherheitsschlüssel implementiert.

+# Onboarding-Backend & Desktop-Identität
+
+Dieses Dokument beschreibt die Backend-Infrastruktur für die Identifizierung und Authentifizierung von
+Desktop-Clients ("Meldestelle-Biest").
+
+## 🚀 Übersicht
+
+Im Gegensatz zur Web-App (die via Keycloak/JWT authentifiziert) nutzen die Desktop-Instanzen für die
+Offline-Synchronisation eine Identität, die während des **Onboarding-Prozesses** lokal vergeben und am Server
+registriert wird.
+
+## 🛡️ Authentifizierungs-Mechanismus
+
+Die Authentifizierung erfolgt über zwei HTTP-Header, die bei jedem Request vom Desktop-Client mitgesendet werden müssen:
+
+| Header           | Beschreibung                                       | Beispiel           |
+|:-----------------|:---------------------------------------------------|:-------------------|
+| `X-Device-Name`  | Der beim Onboarding vergebene Gerätename           | `Meldestelle-PC-1` |
+| `X-Security-Key` | Der beim Onboarding vergebene Sicherheitsschlüssel | `secret-key-123`   |
+
+### DeviceSecurityFilter
+
+Ein Custom-Security-Filter (`DeviceSecurityFilter`) im Backend extrahiert diese Header und setzt einen Spring Security
+Kontext mit der Authority `ROLE_DEVICE`.
+
+## 🛰️ API-Endpunkte (Identity Service)
+
+### 1. Gerät registrieren
+
+Wird beim Abschluss des Onboarding-Screens aufgerufen.
+
+- **URL:** `POST /api/v1/devices/register`
+- **Body:**
+
+```json
+{
+  "name": "Meldestelle-PC-1",
+  "securityKeyHash": "...",
+  "role": "MASTER"
+}
+```
+
+- **Hinweis:** Dieser Endpunkt ist `permitAll()`, um die Erstregistrierung zu ermöglichen.
+
+### 2. Gerät abrufen
+
+- **URL:** `GET /api/v1/devices/{name}`
+- **Auth:** Erfordert `ROLE_DEVICE` oder `JWT`.
+
+## 💾 Datenmodell (Exposed)
+
+Die Tabelle `identity_devices` speichert die registrierten Instanzen:
+
+- `id`: Eindeutige UUID.
+- `name`: Gerätename (eindeutig).
+- `security_key_hash`: Der Sicherheitsschlüssel (gehasht).
+- `role`: `MASTER` oder `CLIENT`.
+- `last_sync_at`: Zeitstempel der letzten erfolgreichen Synchronisation.
+
+## 🛠️ Local Test-Setup
+
+Für lokale Tests mit `curl`:
+
+```bash
+curl -X GET http://localhost:8081/api/v1/devices/Meldestelle-PC-1 \
+     -H "X-Device-Name: Meldestelle-PC-1" \
+     -H "X-Security-Key: secret-key-123"
+```

+
+## 🏗️ Status-Check (Lead Architect)
+
+- **Workflow-Fokus:** Abkehr vom verfrühten Deployment hin zur ehrlichen "Workflow-First" Entwicklung der Desktop-App.
+- **Identität & Sicherheit:** Die App verfügt nun über ein robustes Onboarding-System für die lokale Identität und
+  Sicherheit.
+- **UX-Optimierung:** Die Navigation wurde um Hover-Tooltips erweitert, um die Bedienbarkeit ohne Textlabels in der
+  NavRail zu gewährleisten.
+
+## 👷 Durchgeführte Arbeiten (Frontend & UX)
+
+1. **Onboarding & Setup ("Geburtsurkunde"):**
+  - Komplette Neugestaltung des `OnboardingScreen` (v2).
+  - Erfassung von Gerätename, Sicherheitsschlüssel (Shared Secret) und Datenbank-Sicherungspfad.
+  - Integration von interaktiven Auswahl-Dialogen: `JFileChooser` für Pfade und `PrintServiceLookup` für installierte
+    Drucker.
+  - Einführung des `SettingsManager` zur persistenten Speicherung der Einstellungen in `settings.json`.
+  - Implementierung des `OnboardingValidator` zur Sicherstellung valider Pflichtangaben (Name, Key, Backup-Pfad).
+
+2. **Navigation & Layout:**
+  - Erweiterung der `DesktopNavRail` um ein dediziertes "Setup"-Icon (`AppRegistration`) am unteren Ende.
+  - Auslagerung des Ping-Service ("Sync") als eigenständiges Icon (`WifiTethering`).
+  - Implementierung von **Hover-Tooltips** für alle Navigations-Items (`NavRailItem`) unter Verwendung von Material3
+    `TooltipBox`.
+  - Tooltips sind rechtsbündig (`TooltipAnchorPosition.Right`) positioniert und zeigen den Namen des Moduls ("Admin", "
+    Vereine", "Mails", "Sync", "Setup").
+
+3. **Code-Qualität & Refactoring:**
+  - Bereinigung veralteter Onboarding-Screens und Konsolidierung auf das v2-Datenmodell.
+  - Integration von `@Preview`-Blöcken direkt in den Screen-Komponenten zur IDE-gestützten Entwicklung.
+  - Erfolgreiche Kompilierung des `meldestelle-desktop` Moduls nach Behebung von Typ-Konflikten.
+
+## 🧐 QA-Status & Bekannte Themen
+
+- [x] **Onboarding-Workflow:** App erzwingt Setup bei fehlender Konfiguration.
+- [x] **Drucker-Anbindung:** Systemdrucker werden korrekt gelistet.
+- [x] **Tooltip-UX:** Hover-Effekt in der Navigationsleiste ist aktiv und informativ.
+- [ ] **E2E-Integration:** Die Anbindung des `NennungsEingangScreen` an den echten `mail-service` (Server-Daten abholen)
+  ist der nächste logische Schritt.
+
+## 🧹 Curator's Note
+
+- Die Strategie hat sich von "Live-Gang" zurück auf "Ehrliches Desktop-Fundament" verschoben.
+- Das "Biest" hat jetzt einen Namen und einen Platz für seine Backups. 💾
+
+**Abschluss:** Onboarding und Basis-Navigation sind "Enterprise-Ready". 🚀
