refactor(feed): derive the row's drop-out thresholds from its column widths

They were two hand-written sets of numbers describing the same boxes — change a w-32 and the thresholds are silently wrong, the symptom being a column appearing just before it fits. Now computed from one table (which reproduces the old values exactly). Width also stops reaching the four views that ignore it: it changes every frame of a resize, so passing it everywhere pushed all of them through VideoCard's memo for nothing.
