slab/menuband: tighter popover — chevron-arrow octave, "MIDI" row, smaller insets
Layout pass: less negative space, fewer captions.
Octave control:
- Big monospaced "+0" label (18 pt, semibold) on the left of the title
row, then a tight pair of chevron-arrow buttons on its right.
- NSStepper still drives the value (so controller API doesn't change),
but it's now hidden — the visible UI is just the number + arrows.
octaveDown / octaveUp actions nudge the stepper's integerValue and
call back to controller.octaveShift.
- Reset button removed; the arrows step to 0 just as fast.
MIDI switch:
- Row label simplified from "Send MIDI to DAW" / sublabel "Routes via
virtual port" to a single bold "MIDI" left-aligned, switch on the
right. One line. Half the vertical space.
Popover overall:
- Stack spacing 10 → 6, edge insets 14×16 → 10×12. Trims ~30 px of
vertical filler across the whole popover.
Site:
- Bump download cache-buster query string to ?v=eb9687b.
