Debounce the Audio panel "live" column

Browse Source 
The live indicator compared frames_rendered to the previous UI frame's value, but
audio buffers release in bursts so most frames saw no change -- the cell flickered
between a green dot and grey "idle". Now each stream remembers when it last advanced
and reads "live" for a short window (0.4 s) afterwards, with a ~2 Hz frames/s
estimate next to it; otherwise "idle". Steady and readable for multi-stream games.

Verified: x64 build green. Full visual confirmation needs an injected, audio-playing
game with the per-stream table open (Debug details); logic reviewed.
