feat v1.36.0: marker controls — wall switches that really switch

- marker.controls[]: bound light.*/switch.* entities; explicit per-marker
  tap_action=toggle flips them with HA-group semantics in one call
  (controlsAction + isControllable pure helpers, +2 unit tests, 100)
- icon state and RGB tint mirror the targets (stateless remotes and
  virtual dumb-switch markers finally show something); info card lists
  targets with states; locks filtered everywhere
- chips+search UI in the marker dialog; backend schema; smoke_controls
  (9 checks); TESTING/CHANGELOG same-commit
