ONS marks non-geographic postcodes (no grid reference) with a placeholder
latitude of 99.999999. The "Latest Centroids" export shipped ~12,789 such
rows, which were imported as real postcodes pointing at lat 99.99 and would
poison nearest-station distance maths. Drop them at ingest, with a test.

Each search now stores an `area_label` (district/town) reverse-geocoded from its
coarsened ~1km lat/lng bucket via postcodes.io, surfaced in the Filament Searches
admin as a sortable/searchable column plus an area filter. Geocoding is cached 30
days per bucket, queries a 2km radius so low-density buckets still match the
default 100m miss, and fails gracefully to null. Adds `searches:backfill-areas`
(scheduled hourly) to label existing rows and retry stragglers.
