Tactile feedback (was entirely absent in the app):
- Note long-press to enter selection mode now gives a LongPress haptic
  (wrapped once in NoteItem so it covers both the card click and the
  text tap-gesture paths).
- Checklist drag-reorder fires a haptic on each swap; checklist and todo
  checkboxes fire a light tick on toggle.

Accessibility / dialog polish:
- ColorPicker swatches now reserve a >=48dp touch target via
  minimumInteractiveComponentSize() while keeping the 40dp visual.
- MoveToProjectDialog is height-capped + scrollable so a long project
  list can't overflow off-screen, and each row shows the project color.
