chore(calls): bump @lotusguild/element-call-embedded to 0.25.0-lotus.4

Picks up the fork fix where "Mute Screenshare Audio" was undone whenever the
sharer stopped and re-shared (EC's own volume controls wrote volume 1 through
the same setter). The mute now rides the renderer's `muted` prop like deafen
does. Docs: fork feature table gains the deafen/screenshare-audio row; the
soundboard + quality rows are marked verified end-to-end.
