fix(android): minSdkVersion 23 -> 24 (Porcupine erfordert Android 7+)

@picovoice/porcupine-react-native deklariert minSdkVersion 24, dadurch
schlug der Manifest-Merger fehl wenn die App weiter auf 23 stand.
Android 7.0 ist eh das pragmatische Minimum (Geraete <7.0 sind <1% Markt).

+- Wird zusaetzlich von der f5tts-bridge intern genutzt um den Referenz-Text
+  beim Voice-Upload automatisch zu erzeugen
+
+### TTS-Config
 
 In der Diagnostic unter Einstellungen → Sprachausgabe:
 - **TTS aktiv**: Global An/Aus
-- **TTS Engine**: Piper (lokal, CPU, schnell) oder XTTS v2 (remote, GPU, natuerlich)
-- **Piper**: Standard-Stimme, Highlight-Stimme, Speed pro Stimme
-- **XTTS**: Stimmen-Auswahl, Voice Cloning
+- **F5-TTS Stimme**: Default oder gecloned (Maia etc.)

+3. f5tts-bridge speichert das WAV, schickt einen `stt_request` an die
+   whisper-bridge, legt die Transkription als `.txt` daneben ab und meldet
+   `xtts_voice_saved` zurueck. Der Toast in der App zeigt "Stimme bereit".
+4. Stimme auswaehlen → ein Voice-Preload (stiller Mini-Render) waermt die
