* Add download button for TTS audio
- Add download button next to Play button for all messages
- Button is initially hidden and appears after TTS audio is generated
- Works for both manual play and auto-play modes
- Works for both regular and streaming messages
- Handles cached audio properly
- Download filename includes message ID and voice name
* Refactor: Extract download button logic into helper function
- Create enableDownloadButton() helper to eliminate code duplication
- Replace 4 identical blocks (56 lines) with 4 function calls (4 lines)
- Improves maintainability and follows DRY principle
- Handles both cached and fresh audio in both speakText functions
* Remove hardcoded voice fallbacks, use API or empty list
- Remove hardcoded voice options from HTML dropdown
- Remove all fallbacks to default voices (tts-1:onyx)
- If voices API fails, leave dropdown empty instead of falling back
- localStorage persistence for voice selection already implemented
- Voices API caching already working (1-minute cache like models)
- Voice selection now purely driven by API response
* Fix: Make download button visible after TTS audio loads
- Add download button to previous_messages handler (was missing)
- Change display from "" to "inline-block" for visibility
- Download button now appears properly after TTS processes
* Add debug logging for download button issue
- Add console.log to trace enableDownloadButton execution
- Change === to == for messageId comparison (handle type coercion)
- Log wrapper status, button status, and ID matching
- This will help identify why download button doesn't appear
* Remove debug logging, keep type coercion fix
- Remove console.log statements now that issue is identified
- Keep == comparison (was the actual fix)
- Add comment explaining why == instead of ===
- dataset.messageId is string, messageId param is number
