fix v1.28.1 (revised per owner spec): View-mode cursors and inert openings

- device icons: pointer cursor in View (grab only in Devices mode); click
  behavior untouched
- openings in View: pure drawings always — no cursor/hover/hit/click
- lock badge: the one exception — visible and clickable in View (info card),
  inert in Plan; removed a duplicate pointer-events in .oplock
- smoke covers all cursor/badge cases
