prescreen_status='none' was truthy so it triggered /api/enriched, which only
finds rows already in enriched_domains with NULL status — missing all the
unprocessed domains that only exist in the 72M DuckDB index.
- exclude 'none' from the hasEnrichFilter check
- 'Not checked' now uses /api/domains (DuckDB) and filters client-side:
rows where prescreen_status is absent = never touched
- all other prescreen status values (live/dead/parked/error) still use
/api/enriched server-side
