### What's Wrong?

[BUG] Dictation push-to-talk (press and hold mic) no longer records — click-to-toggle only

### What's wrong
Press-and-hold on the dictation mic button used to start recording for as long as the button was held, and stop on release. On the current build this does nothing; only a single click, which toggles recording on and off, still works.

### Impact
Hold-to-talk is the faster path for short interjections and avoids leaving an open recording session by accident. With toggle-only, every short addition needs two clicks plus a confirmation.

### What Should Happen?

### Expected
Press and hold records while held and stops on release, as before.

### Error Messages/Logs

```shell

```

### Steps to Reproduce

### Steps to reproduce
1. Open a chat with an empty composer.
2. Press and hold the mic icon, speak, release.
3. Nothing is recorded and no transcript appears.
4. Single-click the same icon: recording starts and works normally.
