v2.11.0 — Alternate barcodes: the relabeled return scans home

Minor release. One additive migration (new empty table).

Operator-facing

Alternate barcodes per product. Relabeled units — marketplace FNSKU stickers, vendor labels — now scan home on every floor surface: station console, PDA pick/pack, receiving, and returns. Add them on the product form (“Alternate barcodes”); each code is unique across the whole catalog, enforced at capture with a named refusal (BARCODE_TAKEN — {barcode} already resolves to {sku}). The alias resolves — documents and the ledger always name the real SKU.

Returns receiving gains scan-to-verify: scanning locates and focuses the line (wrong product refuses by name); quantities stay operator-confirmed.

Known issue (fix in v2.11.1, in progress)

Deactivating and then reactivating an alias fails with a self-collision refusal; the alias stays inactive. Workaround: delete-and-recreate is not available by design — wait for v2.11.1 before relying on reactivation.

Rollback

Re-deploy v2.10.0. New table is ignored by old code.
