Two production bugs from VENDING (order 485224762, 2026-04-22):
1. Oracle: ORA-20000 when a GoMag order contains a kit SKU whose expansion
includes CODMAT X plus a second item with SKU=X. Two article-insert
call-sites in PACK_IMPORT_COMENZI bypassed merge_or_insert_articol —
line 622 (NOM_ARTICOLE fallback) and line 538 (kit discount line).
Both now use merge_or_insert_articol for consistent dedup semantics.
Regression test added in test_complete_import.py covering the exact
kit-plus-direct scenario.
2. SQLite: retry_service._download_and_reimport refreshed orders row but
never repopulated order_items. Combined with mark_order_deleted_in_roa
(which wipes items), any retry/resync left the UI showing "Niciun
articol" despite successful Oracle import. Retry now rebuilds items
from the fresh GoMag download on both success and error paths,
mirroring sync_service.
Includes scripts/backfill_order_items.py — one-shot recovery for orders
already in this bad state. Reads settings, re-fetches from GoMag,
rewrites order_items without touching Oracle or order status.
