fix v1.28.1: openings fully inert in View mode

- op-hit: pointer-events none + default cursor by default; interactive (grab,
  hover outline, drag) only inside Plan; lock badge is a pure indicator
- opening click edits in Plan with any tool; no interaction whatsoever in View
- smoke_inert_openings.mjs; TESTING.md updated
