feat(state_511_atis): Castle Rock 511 adapter — Idaho incidents/closures/road work (v0.9.2)

Second CENTRAL_TRAFFIC adapter. Production code; central-supervisor + central-gui
restart (new adapter class + ADAPTER_GROUPS). No new stream -> no archive restart;
migration 026 adds the adapter row only. Ships disabled.

Two-endpoint join per layer: GET /map/mapIcons/<Layer> (markers: itemId + coords)
joined on id with POST /List/GetData/<Layer> (DataTables detail: roadwayName,
description, county, severity). The marker feed has coords but no text; the List
feed has text but no coords.

Layers -> event_types (wzdx category/subject precedent): Incidents->incident,
Closures->closure, Construction (type "Roadwork")->work_zone. category is
"<event_type>.state_511_atis"; subject central.traffic.<event_type>.<state>.
Severity 3 if isFullClosure else 1. Cadence 300s. Dedup inherited from the
v0.9.1 SourceAdapter mixin. enrichment_locations canonical (latitude,longitude)
from the marker join; county/state come upstream.

Templatized per state via settings {"states":[{code,base_url}]} but ships
Idaho-only: cross-state spot-checks refuted the shared-URL hypothesis (Oregon
TripCheck is HTML, Wyoming wyoroad 404 -- neither is Castle Rock). Add states as
settings rows once each host is verified.

Also fixes a latent test bug: test_consumer_doc per-adapter heading regex was
[a-z_]+ (no digits); state_511_atis is the first adapter name with digits, so
widened to [a-z0-9_]+.

Full suite: 759 passed, 1 skipped (central and unprivileged zvx, 3x each).
