Import against a live MoySklad account crashed with PostgreSQL 22001 after
loading 21500/~N products: Article column was varchar(100), but some MoySklad
items have longer internal codes, and Barcode.Code needed to grow for future
GS1 DataMatrix / Честный ЗНАК tracking codes (up to ~300 chars).
- EF config: Product.Article 100 → 500, ProductBarcode.Code 100 → 500.
- Migration Phase1e_WidenArticleBarcode (applied to dev DB).
- Defensive Trim() in the MoySklad importer for Name/Article/Barcode so even
future schema drift won't take the whole import down.
