feat v1.23.0: doors & windows with live open/lock state

New markup tool 'Opening': click a wall — the opening snaps onto the nearest DERIVED
room wall (v1.19.0 model: openings keep absolute coords, so room edits never break
them) and takes its angle. Dialog: type, length in real cm (door 90 / window 120 —
per-space scale makes it honest), contact sensor (invertible), lock (doors).
Rendering after easy-floorplan (MIT): hinged leaf + swing arc drawing on via
stroke-dashoffset; window = two casements. No sensor → static plan defaults (door
open, window closed); unavailable freezes the default (pure openingAmount, tested).
Lock: padlock badge (green locked / orange unlocked / grey unknown); the lock is
never toggled from the plan — clicking shows an info card with both states.
snapToWall + openingAmount in logic.ts; space.openings validated server-side.
+2 tests (76). Verified live on the dacha (real TTLock + TRV window sensor).
