Fix Edge TTS voice fallback and Gemini voice validation

- Edge TTS fallback list now includes fr-FR-RemyMultilingualNeural
- Removed 'Neural not in voice' check that rejected Gemini voices (fr-FR-Standard-A etc) before falling back - these are valid voices and Edge-tts handles them properly
- Improved is_male check to match 'Remy' not 'Remi'
