feat(gallery): bring ten core controls to the extraction bar

Batch 2 of the extraction sweep: consoleKeys, abcKeypad, indexPlate, faderH, faderV, knob, segmented, chipToggle, armButton and lampRow now carry the split-flap-shape contract comment. Every class they own wears the dupre- prefix, internals and modifiers included (dupre-key dupre-green, dupre-fader dupre-cap), with every in-kit consumer updated in the same pass: the dsky and annunciator pads, the rotarySelector and encoder spindles, the page's size bar, and the probe selectors.

I also removed indexPlate's dead '#dupre-defs' lookup (nothing ever created that id) and dropped the unused .key.off rule. The faders, knob and lampRow now cache their element refs instead of re-querying every set(), and segmented and lampRow clamp set() the way consoleKeys does.

The audit's contract count moves from 14 to 24 of 111.
