Fix: ComboSetting support for QStringList models and multiple model types

- Add type detection for three different model types:
  - QStringList (video devices): plain strings
  - Audio devices: objects with {id, display_name}
  - Simple entries (language, color): objects with {text, value}
- Set textRole: "" for video devices ComboBox (QStringList)
- Fix ComboBox popup background color for dark mode
- Add window background color to CallsWindow for dark mode
- Update documentation

+## 4. ComboSetting unterstützt verschiedene Model-Typen
+
+### Problem
+Die ComboSetting-Komponente konnte nur mit einem Model-Typ umgehen. Es gibt aber drei verschiedene Typen:
+1. **Audio-Geräte**: `QVariantList` mit Objekten `{id: "...", display_name: "..."}`
+2. **Einfache Einträge**: `QVariantList` mit Objekten `{text: "...", value: "..."}`
+3. **Video-Geräte**: `QStringList` mit einfachen Strings
+
+### Symptome
+- Audio-Geräte (Lautsprecher, Mikrofon, Klingel) wurden nach Neustart nicht korrekt angezeigt
+- Kamera-Dropdown zeigte keine Gerätenamen an (nur leere Einträge)
+
+### Lösung
+**Datei:** `Linphone/view/Control/Button/Settings/ComboSetting.qml`
+
+Die `currentIndex`-Berechnung, `onCurrentIndexChanged` und `Binding.value` wurden erweitert, um alle drei Typen zu erkennen und korrekt zu verarbeiten:
+
+```qml
+currentIndex: Utils.findIndex(model, function (entry) {
+    var currentVal = propertyOwnerGui
+        ? propertyOwnerGui.core[mainItem.propertyName]
+        : propertyOwner[mainItem.propertyName]
+    // Handle different entry types
+    if (typeof entry === 'string') {
+        // QStringList (video devices): compare strings directly
+        return entry === currentVal
+    } else if (entry.id !== undefined) {
+        // Audio devices: compare by id
+        return currentVal && entry.id === currentVal.id
+    } else if (entry.value !== undefined) {
+        // Simple entries (language, color): compare by value
+        return entry.value === currentVal
+    }
+    return false
+})
+```
+
+**Datei:** `Linphone/view/Control/Form/Settings/MultimediaSettings.qml`
+
+Für die Kamera-ComboBox wurde `textRole: ""` gesetzt, da QStringList-Models keine Properties haben:
+
+```qml
+ComboSetting {
+    id: videoDevicesCbox
+    entries: SettingsCpp.videoDevices
+    propertyName: "videoDevice"
+    propertyOwner: SettingsCpp
+    textRole: ""  // Empty for QStringList models
+    // ...
+}
+```
+
+### Technischer Hintergrund
+
+| Model-Typ | Beispiel | Vergleich | Rückgabewert |
+|-----------|----------|-----------|--------------|
+| QStringList | `"V4L2: /dev/video0"` | `entry === currentVal` | `entry` (String) |
+| Audio-Geräte | `{id: "pulse:0", display_name: "Speaker"}` | `entry.id === currentVal.id` | `entry` (Objekt) |
+| Einfache Einträge | `{text: "English", value: "en"}` | `entry.value === currentVal` | `entry.value` (String) |
+
 ## Zusammenfassung der geänderten Dateien
 
 | Datei | Änderung |
 |-------|----------|
-| `ComboSetting.qml` | valueRole/textRole und korrekter Wertvergleich |
+| `ComboSetting.qml` | Unterstützung für drei Model-Typen (QStringList, Audio-Geräte, einfache Einträge) |
+| `MultimediaSettings.qml` | `textRole: ""` für Kamera-ComboBox |
 | `TextField.qml` | Binding nach Windows-Workaround wiederherstellen |
 | `ComboBox.qml` | Popup-Hintergrundfarbe für Dark Mode |
 | `DisplaySettingsLayout.qml` | Tippfehler bei Farbname korrigiert |
