Initiating a call in a 1:1 room without speaking permission will cause an infinite loop.

### Steps to reproduce

1. Enter a 1:1 room that does not have permission to speak;
2. Tap the voice call or video call button in the upper right corner of the screen.

### Outcome

#### What did you expect?
The logic is the same as the Android version, the voice call or video call button on the top right corner of the screen is not available in the 1:1 room without speaking permission.

#### What happened instead?
The voice call or video call button in the upper right corner of the screen is available at this time, but then it prompts `You don't have permission to post that to the room. user_level (0) < send_level (100)`.
**This warning will appear in an endless loop, Unless you restart the app after killing it.**
**Also the proximity sensor will be activated until the app is restarted.**

Reproduce the issue by entering a 1:1 room without speaking permission and tapping the voice or video call button. Start by tracing those buttons through the permission-error path, then verify that the buttons are unavailable and that neither the warning nor proximity sensor remains active.
