🐛 Bug: Fix misleading model mappings and incorrect comments

[ManvithGopu13]

Code Issues

Problems Found:

1. Misleading Model Mappings

   • All model options map to the same actual model:
     • Image route: All map to stabilityai/sd-turbo
     • Audio route: All map to microsoft/speecht5_tts
   • Users expect different models but get the same one

2. Incorrect Comments

   • routes/audio/audio.py:16: Says "Video generation request received" (should be "Audio")
   • routes/audio/audio.py:38: Comment says "Generate image" (should be "Generate audio")
   • routes/audio/audio.py:43: Comment says "Convert image to base64" (should be "Convert audio")
   • routes/audio/audio.py:50: Comment says "Return base64 image data" (should be "audio")

3. Wrong Default Model

   • routes/audio/audio.py:13: Default model is 'stabilityai/stable-diffusion-2-1' (image model) instead of audio model

4. Commented Out Code

   • routes/audio/audio.py:2: Unused import commented out
   • functions/audio/audio.py:31-43: Large commented code block should be removed

Recommended Fixes:

• Implement actual different model mappings or remove misleading options
• Fix all incorrect comments
• Fix default model in audio route
• Remove commented code or document why it's kept
