Relink migrated JE source_id to Arcus order/invoice UUIDs

A migrated historical journal entry is born with source_id holding the source-system (Versa) document INTEGER, because historical GL is loaded BEFORE orders/invoices: the Arcus order/invoice UUID does not exist yet. Native Arcus order JEs set source_id = the Arcus order UUID, and the GL UI / reports resolve the source document by that UUID.

This endpoint is the corrective reconciliation pass run AFTER orders and invoices are migrated. The caller supplies a batch of items, each mapping a source-system journal id (external_id, carried on journal_entries.external_id) to its Arcus order/invoice UUID (source_id).

Strict-resolve safety. source_id must be a UUID that resolves to an order in the entity (or a vendor_bill when source_module=‘ap’ or new_source_type is AP_BILL / AP_PAYMENT, added 2026-05-27). A non-UUID or non-resolving value is rejected, never written — this prevents re-stamping a source-system integer or mislinking across entities.

Idempotent. When a JE already carries the target source_id (and the target source_type and description match), the item returns relinked=false (no-op). Re-running the whole pass is safe.

Scope guard (relaxed 2026-05-27 MIGRATION-MAPPING-NATIVE). Only journal_entries whose external_source = 'versa_cloud' can be matched. Previously also required source_type = VERSA_MIGRATION; relaxed so the handler can relink rows that the loader has already classified to canonical source_types (PAYMENT, INVOICE, AP_BILL, etc). is_historical_import is asserted as a belt-and-suspenders guard. Native Arcus JEs (external_source IS NULL) are never matched.

Optional source_type upgrade (new_source_type, added 2026-05-27). When supplied, upgrades source_type from VERSA_MIGRATION to a canonical Arcus value. The handler never downgrades a canonical source_type back to the fallback.

Optional description enrichment (enrich_description, added 2026-05-27). When true, rebuilds description from the canonical native template with the order_number suffix. Non-order-attached source_types (INVENTORY_ADJUSTMENT / MANUAL / BANK_RECON / BANK_DEPOSIT) are skipped to preserve the Versa memo carried by the loader.

Pure header UPDATE. Touches only journal_entries.source_id, source_module, source_type, and description. No line is touched, no amount is touched, no FK is created or dropped.

Scope: migration:write.
