feat(localAdsb): render on Navara

Task 12b. src/layers/localAdsb/render/navara.js implements the Local
ADS-B renderer interface of 12a on Navara:
- markers: the shared aircraft renderer's glyph sets in magenta #ff4fd8
  (class silhouette and scale, ×3 near / ×0.5 far, always on top), drawn
  under every sprite layer as Cesium draws the entities; each frame writes
  what Cesium's CallbackProperties gave (position, screen rotation,
  visibility) and the 2,000 km display distance;
- the 978 MHz UAT ring: its own sprite set, a white ring atlas tinted
  #ffb3ef, Cesium's 24 px point plus its 1.5 px outline (27 px), the same
  distance scale and distance, pickable as its aircraft;
- models (the Flights GLBs, magenta MIX tint), trail and head: the shared
  aircraft renderer's; the camera never follows a local aircraft.
Registered by registerNavaraLayerRenderers (import()); the Navara catalog
now offers flights, military and local ADS-B.

- ?qaFeed=local-adsb:fixture: the local receivers' answer in the server's
  format (src/bench/w1Feeds syntheticLocalReceivers: 40 aircraft near JFK,
  10 on 978 MHz UAT) through the layer's own decoder-feed session
  (sources.localAdsbFeeds, null by default: the layer makes its own).
- qa-w1-layers --layer=local-adsb: a click selects a marker and shows its
  card with the receiver line, the camera does not follow, Escape leaves
  the selection (it never answered Escape), empty map releases it.

qa-w1-layers local-adsb: Cesium 12/12, Navara 13/13, --compare parity
(global pose: the 2.27 px camera offset only). qa-flights-engines
--layer=local-adsb: 14/14 (fills exact; UAT rings side by side in
docs/migration/phase3/localAdsb).
