feat(sim): board-agnostic microphone seam + reSpeaker gallery glyph 

setMicrophoneSource on the simulator shim mirrors addI2CDevice: a part
that produces audio hands one 16-bit sample per call to whatever bridge
implements the method (the in-browser JS-engine bridges); everywhere
else the optional chain makes it a silent mic. No board-kind checks in
components. Plus the flat reSpeaker Lite glyph for gallery cards.
