-- Add 'processing' to the verification_requests status check constraint.
-- This was missed when Phase 1 changed the OCR success update from 'verified'
-- to 'processing'. Without this the constraint fires on every OCR success, the
-- .catch() handler misclassifies the failure as EXTRACTION_FAILURE, and the
-- verification is routed to manual_review before live capture is ever shown.
