Move waterfall controls to function bar and fix SDR claim race on tune

Browse Source 
Move waterfall controls from the sidebar into a function-strip bar inside
#listeningPostVisuals so they sit directly above the waterfall canvas.
Also fix the "SDR device in use" error when clicking a waterfall frequency
to listen — the WebSocket waterfall's device claim wasn't being released
before the audio start request because the backend cleanup hadn't finished.
