Microphone stays active after interview has ended

In the interview player / post‑interview state, the microphone appears to remain active or ready to record even after the interview has ended. I expected the microphone and any push‑to‑talk interaction to be fully disabled once the session is over.

Steps to Reproduce

1. Start an interview session and speak with the agent for at least one question.

2. End the interview (either via the current end flow or by reaching the final question).

3. After the interview is over, attempt to speak again or press the push‑to‑talk key (spacebar).

4. Observe whether the mic visualization and/or agent behavior suggests that audio is still being captured.

Actual vs Expected Behavior

Actual: After the interview ends, the UI still suggests that the microphone can be used (e.g., mic icon appears live, waveform/levels may still react, or the agent still responds), implying that audio is being captured outside of an active session.
Expected: When the interview is over, the microphone should be fully disabled for that session: no more recording, no mic visualization responding to speech, and no further agent responses unless a new session is explicitly started.

Additional Context (optional)

This is both a UX and trust/privacy concern; users should feel confident that the app stops listening once the interview is finished.
