On-Ledger Transfer Batch Screen

Batch-level pre-commit sanctions and purpose-code screen for a shared-ledger transfer batch, modeled on the shipped screen_tip20_transfer_batch pattern: per-transfer status, screening-list hits, purpose-code validity, a batch-clean verdict, and coverage gaps. Reuses the same purpose-code enum and screening-hit shape as check_purpose_code_requirement / check_screening_list_coverage rather than duplicating their logic. Zero-network; screens against supplied flagged-name lists only.
