feat(v2): add data-quality audit queue for INSUFFICIENT_CONTEXT, require non-empty next_action

buildDataQualityReview extracts an auditable record per INSUFFICIENT_CONTEXT
ticket (ticket_id, title, ai_reason, context_size, has_description,
followup_count, task_count, has_solution, last_interaction_at) -- not sent
anywhere, just for calibration. Also tightened validateAiClassification to
reject an empty/whitespace-only next_action (was previously accepted).
