feat(iit): Implement real-time quality control system

Summary:

- Add 4 new database tables: iit_field_metadata, iit_qc_logs, iit_record_summary, iit_qc_project_stats

- Implement pg-boss debounce mechanism in WebhookController

- Refactor QC Worker for dual output: QC logs + record summary

- Enhance HardRuleEngine to support form-based rule filtering

- Create QcService for QC data queries

- Optimize ChatService with new intents: query_enrollment, query_qc_status

- Add admin batch operations: one-click full QC + one-click full summary

- Create IIT Admin management module: project config, QC rules, user mapping

Status: Code complete, pending end-to-end testing
