Move mic to preview row + restructure bottom bar + hide avatar when signed out

Mic button/sound bar/slider moved from footer into the preview pane
(vertically below the Socials+TRAX row). Bottom bar reduced to a single
row: gear icon left, stream stats centered under preview, resolution
dropdown right. Avatar image only loads when IsConnected fires true — no
stale image from a previous session on startup. Build 0w, 247 tests.
