Introduce server TTS support and engine selection while keeping device TTS as the default. - Add new persistence keys for storing TTS engine and selected server voice (ttsEngine, ttsServerVoiceId, ttsServerVoiceName). - Extend TextToSpeechService to support two engines: TtsEngine.device (FlutterTts) and TtsEngine.server (remote audio). - Wire in an AudioPlayer and optional ApiService to fetch raw audio bytes from the server and play them, with event hooks mapped to existing lifecycle callbacks. - Implement fallback to device TTS on server errors or empty responses, and ensure player lifecycle (pause/stop/dispose) is handled when using server engine. - Allow engine and preferred voice to be configured before initialization and updated at runtime via updateSettings. This enables selecting a server-side voice and using a remote TTS provider while preserving compatibility with the existing device TTS implementation.
