Archive Suppliers

Suppliers can now be archived, the same way warehouses already can. Archiving hides a supplier from the default supplier list and pickers while preserving every historical link — purchase orders, product relationships, receipts — untouched. It is fully reversible.

Archive lives on the supplier detail header. If the supplier still has open POs or linked products, the confirmation shows those as advisory warnings but leaves the button enabled — the pattern is warn, don't block. Archived suppliers get a top banner with a one-click Unarchive. The suppliers list picks up an Archived filter (Include archived / Archived only), and the default view hides archived rows.
