feat(client): district morphology generation overlay in the Atlas (T-1046, D-226)

Client half — the cascade's district tier is now visible in the Atlas map.

- protocol.gd: decode the district_grid field from AtlasLayerResponse.
- atlas_viewer.gd: a gen_district ('MRPH') toggle in OVERLAY_DEFS + the
  district-grid generation state (set/get) + wire it from the Ready response.
- atlas_marker_overlay.gd: _draw_gen_district() paints the coarse cols×rows grid,
  each cell coloured by its MorphologyZone discriminant (D-239 §6, 17-zone
  palette), semi-transparent under the Layer-1 line overlays. Planetary map view
  (not the 2km on-demand districts — those are Phase 5 in-world).

gdUnit4 test: overlay registered + district grid round-trips through the viewer
and the protocol decode. Visual tuning of the palette can follow once eyeballed
in the running Atlas.
