fix v1.36.3: door sectors no longer punch dark wedges inside the room

- room outline + sectors as separate clipPath children (always union)
  instead of subpaths of one nonzero path where opposite windings
  cancelled the overlap; smoke asserts one contour per path

+- Glow: fixed dark wedges appearing INSIDE a lit room near some doorways.
+  The room outline and the door sectors were subpaths of a single clip path;
+  with opposite winding directions the nonzero fill rule cancelled their
+  overlap. Each contour is now its own clipPath child (children always
+  union), so sectors only ever ADD light.

 ## v1.36.2 — 2026-07-23
 - **Glow radius is now per source**: every device dialog gained a "Glow
   radius" field (in your HA units; empty = the global default from general
