Merge main into prereq-10-osm-overlays and port Open Map Overlays

Main moved on since this PR opened; the overlay layer is ported to the
current contracts:

- Layer-state token 6 (j belongs to transit; new single-character
  tokens are digits) with a reservation-ledger row, and the option owner
  renamed to the layer id so the compact share codec can encode it.
- Constructed per catalog by createOsmOverlaysLayer() in
  constructCatalog.js; src/standalone/data.js no longer registers layers.
- Drapes through maps/imageryHost.js, so the overlays show on Google 3D
  (tileset imagery) as well as the globe stacks, and follow map-stack
  switches. Imagery layers are created on enable and destroyed on
  disable/destroy.
- Translated chip labels and layer name in every locale, LAYER_NAME_KEYS,
  Infrastructure panel group, voice manifest entry.
- Attribution: OpenSeaMap tiles CC BY-SA 2.0, OpenSnowMap credit as
  required, OSM ODbL credit for both; bulk-download note in DATA_SOURCES.
- CURRENT-STATE row, changelog fragment, share-codec absent defaults,
  updated token-ledger fixtures and voice schema pins.
