Feat: ElevenLabs als Premium-TTS-Engine (sauberes natives Deutsch, Voice Library)

Browse Source 
Sidecar: /tts + /voices + /health um Engine `elevenlabs` erweitert (Flash v2.5, Key zur Laufzeit
aus env ODER ~/.hermes/.env → Nachtragen ohne Deploy). Default bleibt Piper. Frontend: ElevenLabs
im Stimm-Picker (fest sichtbar) inkl. „Key fehlt"-Hinweis + Quota-Note. Chatterbox-DE war zu akzentig.
