Clearer Audio Warnings During a Session (v3.9)

Hedy is more precise about what it is hearing.

Barely-audible input and stopped audio are now told apart, so the warning matches the actual problem.
The wording no longer assumes a broken microphone, because the cause is often a muted app or a device that switched away.
The level indicator flattens when capture is unhealthy, so you can see the problem at a glance.
Tapping the warning opens Microphone Settings directly.
