[FEAT] Auto-play audio responses in gradio

[NeonDaniel]

Objective

Add option or default behavior to play TTS with Gradio responses.

Initial Implementation Requirements

• checkbox or other UI element to enable/disable auto-play

Other Considerations

• Associate audio with specific chat messages to better handle history and remove extra UI element
• Some inputs will have multiple responses which are currently not handled

[NeonDaniel]

Just need a checkbox option that disables auto-play to close this issue
