Mobile: resume live voice in the same existing task after a dropout

What variant of Codex are you using?

Mobile Codex live voice. Mobile OS and app version were not provided.

What feature would you like to see?

Allow a dropped live Codex voice session to be restarted or resumed in the same existing task on mobile.

Reported sequence:

1. Start a live Codex voice session on mobile.
2. The voice session drops.
3. Reopen the existing chat/task.
4. Only text input/dictation is available; there is no way to restart or resume live Codex voice within that same task.

Expected behavior: provide a Resume voice or Start voice action in the existing task after a dropout, retaining the task's conversation context so the spoken conversation can continue.

Impact: a dropout breaks conversational continuity because the user cannot continue in live voice in the same task. Dictation does not restore the live voice session.
