Daniel Onyejesi 1f84a58813 Upgrade TTS to ElevenLabs Adam voice with frontend integration
- Switch speakText() to call /api/text-to-speech backend (ElevenLabs) with fallback to native speechSynthesis
- Upgrade ElevenLabs voice from Rachel to Adam (pNInz6obpgDQGcFmaJgB) — warmer, more professional
- Upgrade model from eleven_monolingual_v1 to eleven_turbo_v2_5 for better quality and lower latency
