feat(persistence): v19 schema — fire enrichment columns

Browse source 
Add nullable fire_cause, unique_fire_id, geocoder_city columns to the
fires table (additive migration, no backfill) and bump SCHEMA_VERSION
18 -> 19. Validated in production on CT 108 (schema_meta.version=19,
clean run); commits the finished fire-spam/danger-zones migration that
was live but uncommitted.
