The record button appears on Matrix too

The same button, because the daemon (nobilis 3017437) now speaks both shapes
from one recording: Discord's flag and base64 waveform, Matrix's MSC3245
marker and integers. Nothing about the control changes - it is a microphone,
a clock and a level meter either way - and the pill that plays one back
already drew a Matrix voice message the moment the daemon started reading it,
since both arrive as the same attachment.
