fix : play back icon for the downlaoded tts

[novenaurion]

Summary

Chat TTS clips already attached to a message now show a play icon instead of the speaker, so downloaded audio can be replayed without queueing TTS again.

Why

This change is needed because Core stores message audio as type: "tts" and format: "audio". The UI looked for type === "audio", so getMessageAudioUrl always returned null. The problem it solves is the TTS control staying on speaker even when assets[] already had a ready MP3 URL.

Changes

• Changed src/modules/ai/types.ts findMessageAudioAsset to match item.format === "audio" instead of item.type === "audio"

Testing

This change was verified by opening an assistant message that already has a TTS asset (format: "audio", url present). The control should be play (or stop while playing), not speaker. Tapping play should use the existing URL, not queue another TTS job.

• Unit tests
• Integration tests
• Manual testing
• Existing test suite passes

Notes

No API or migration change. metadata.tts_status is not used for the icon. Existing messages with type: "tts" and format: "audio" start matching immediately.
Unit tests for this helper were not added in this commit (one-line match fix only).
