One settings table in CameraBridge watches every camera value into the telemetry tick and backs a generic setCameraValue, so the tabbed camera menu (Exposure / Photo / Video / Other) is built from row specs and the camera's own capability ranges. Writes show at once and fall back to what the camera reports. Adds the quick exposure panel (Auto/A/S/M, ISO slider, shutter and aperture wheels, EV strip, metered EV in M), a new camera column with record timer and interval/pano progress, a zoom column for zoom cameras, tap-to-focus / tap-to-meter, and a live histogram.
