fix(wzdx): persist current work zones to traffic_events via dedicated ingest (#109)

The WZDx daily summary + DM query count from traffic_events, but work
zones weren't landing there: wzdx rode the generic _delta_emit path,
which silent-seeds the seen-set and returns before the decider's INSERT
on the cold-start first poll, so the current zone set never persisted
(summary would count ~0). Add a dedicated _ingest_wzdx (mirroring the
fires ingest) that UPSERTs every current coalesced zone into
traffic_events each poll (persist-only, last_broadcast_at=NULL, no emit,
no broadcast) and reconciles zones that drop out of the feed (never wipes
on an empty/failed fetch). Per-event work-zone broadcast stays suppressed
(the decider's work_zone gate is untouched). Retargets 4 tests in
test_store_received_delta.py that used a fake 'wzdx' source to exercise
the generic gate onto a neutral routing name.

+# NOTE ON ADAPTER NAME vs EVENT SOURCE
+# ------------------------------------
+# These durable-pre-seed / received-delta-gate tests exercise the store's
+# GENERIC emit path (store._delta_emit + _seed_from_persistent), which keys the
+# seen-set and the "seeded" marker on the event's SOURCE ("wzdx"/"511"/
+# "usgs_quake"), NOT on the adapter's registration name. The name only selects
+# the _ingest routing branch. Native ``wzdx`` now has a DEDICATED persist-only
+# ingest (store._ingest_wzdx) that upserts traffic_events and NEVER emits, so a
+# ``_FakeWZDx`` injected under the literal name "wzdx" would take that path and
+# broadcast nothing. To keep testing the GENERIC gate with an external_id-keyed
+# source, these tests inject the ``source='wzdx'`` fake under the neutral
+# routing name ``_GENERIC_NAME`` (the else-branch → _delta_emit), while every
+# assertion still references the durable SOURCE "wzdx". Real wzdx persistence is
+# covered separately in test_store_wzdx_persist.py. The name is arbitrary as
+# long as it is NOT one of the _ingest special branches (swpc/ducting/nifc/
+# generic_http/wzdx/avalanche); anything else routes to the generic else path.
