docs: catch all documentation up to v1.23.1

- READMEs (en+ru): doors/windows/locks section (openings tool, live rendering, drag,
  double-click properties), presence ripples + per-device icon size/rotation in the
  manual-marker section.
- ARCHITECTURE: room geometry rules (derived walls, no-overlap, merge/split via
  polyclip-ts and why not polygon-clipping), doors & windows model (space.openings,
  snapToWall, absolute coords, security), per-marker display fields + cell_cm ruler.
- DEVELOPMENT: gotchas — polygon-clipping ESM/types mismatch; same-version redeploys
  keep ?v so browsers cache the old bundle.
- STATUS: snapshot refreshed (releases to v1.23.1, dacha deployed v1.23.1), milestones
  v1.17–v1.23.1 incl. the lost-sources lesson (push right after building).
- ROADMAP: 8 shipped Quality-Scale items ticked (done since v1.12.0).
- TESTING: restored the v1.22.0 ripple checklist lost in the sandbox reset.

+## Presence ripples / per-device icon (v1.22.0)
+
+- [ ] Marker dialog → Display = "Ripple only": the icon badge disappears, rings pulse while the
+      entity is on, and collapse to a faint dot when it goes off
+- [ ] Display = "Icon + ripple": both the icon and the rings are drawn
+- [ ] Ripple colour and size (×2..×8) apply per device
+- [ ] An entity going `unavailable` stops the pulsing (idle dot), never leaves it running
+- [ ] Icon size ×0.5..×3 and rotation 0..350° apply per device; the temp/humidity badges
+      scale with the icon
+- [ ] Ripples still work with the card-wide "live states" toggle OFF (they are opt-in per device)
+- [ ] With OS "reduce motion" enabled, rings do not animate

 ## Doors & windows (v1.23.0)
 
 - [ ] Markup → "Opening": a click away from any wall shows a toast; near a wall — the dialog
