Merge origin/main into german/navara

Conflict resolutions:
- src/main.js: upstream's PHOTON_URL place-search setting is read once at
  module level and passed as geospatial: { endpoints: { photon } } by
  createApplication(), so every engine start of the switch flow gets it; the
  old single top-level createStandaloneApplication() call stays removed.
- src/layers/bikeshare/render/cesium/rendering.js: upstream's
  publishedCapacity fix applied with this branch's
  resolveCapacity(model, capacity, status) signature. The same fix is ported
  to src/layers/bikeshare/render/navara.js (record.publishedCapacity, status
  polls resolve from it), with a Navara regression test; upstream's
  proxyRoute test imports the moved render/cesium/rendering.js.
- src/layers/traffic/flow.js: upstream's nextTask() yield and current()
  check kept before the scene is taken from this branch's
  _trafficScene?.() ?? _viewer?.scene with its missing-scene return.
- scripts/package-boundaries.json, scripts/format-scope.json: union of both
  sides' file lists.
- src/voice/actionSchemas.test.mjs: both history comments kept, payload hash
  recomputed for the merged schemas (Sentinel-2 map stack enum plus the
  shorter layer alias hint).
- src/hudAltitudeDatum.test.mjs: this branch's engine-based IntelHUD
  construction with upstream's placeLabels summary context.
