Title: Enhanced Voice Configuration Support in Character Cards

Description
Previously, voice settings from character configuration were not being properly respected when ElevenLabs was not in use. This enhancement adds comprehensive voice configuration support in character cards for both VITS and ElevenLabs, with proper fallbacks.

Changes Made

• Voice settings from character configuration are now properly used for both VITS and ElevenLabs
• Automatic fallback to VITS when ElevenLabs API key is not present
• Made ElevenLabs configuration fields optional in schema
• Added better logging for voice selection process
• Added support for full ElevenLabs configuration in character cards

Example Character Configuration

{
    "settings": {
        "voice": {
            "model": "en_GB-alan-medium",  // For VITS
            "elevenlabs": {   // Optional ElevenLabs configuration
                "voiceId": "your-voice-id",
                "model": "eleven_monolingual_v1",
                "stability": "0.5",
                "similarityBoost": "0.75",
                "style": "0",
                "useSpeakerBoost": "true"
            }
        }
    }
}
