Lets a user export the current ROI as one CSV with a column per selected
angle's value (RF peak freq, Bias A, Bias B, or velocity), once angles share
a common (x, y) grid -- either via a live Fusion alignment result or because
the open file is itself a previous Alignment Wizard export whose angles
already share one grid on disk. Never triggers a background compute; angles
without cached/stored data for the chosen value type are simply unavailable
in the picker.
