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

rotarySelector, slideRule, rocker, transport, presetBank, dualKnob, encoder, keySwitch, crossfader, and thumbwheel get contract comments, dupre- prefixed CSS, and cached element refs. presetBank and dualKnob set() now clamp out-of-range input, with a probe check covering both. rotarySelector and keySwitch cap their inputs at the five- and three-stop plates they draw. The audit's contract count moves to 34/111.
