fix(desktop): scope audio endpoints to the active profile

transcribeAudio/speakText/getElevenLabsVoices called the backend without
profileScoped(), so for a non-default profile they hit the default backend
config instead of the active profile - playback used the wrong TTS/voice
even though settings were saved to the active profile config.

Fixes #53441
