Preview-Modelle liefern gelegentlich HTTP 200 mit leerem Body (oder 5xx) -> bisher
brach das die ganze Sprech-Runde ab ('empty audio content', 502). Jetzt bis zu 3
Versuche mit linearem Backoff; 4xx (z. B. ungueltige Stimme) wird sofort gemeldet
(kein Retry). Damit klappt das Durchprobieren von Stimmen zuverlaessig (Live-Test:
alle 20 getesteten Gemini-Stimmen inkl. Leda liefern Audio).
Tests: tests/test_openrouter_tts.py (leer->ok, 4xx sofort, alles-leer, 5xx->ok).
Doku-Hinweis in BEDIENUNGSANLEITUNG.
