fix(mappings): resolve 409 error on multi-CODMAT edit and make SKU editable

Batch create after soft-delete was rejected because create_mapping()
treated soft-deleted records as conflicts. Added auto_restore param
that restores+updates instead of 409 when called from edit flow.
Also removed readOnly on SKU input in edit modal.
