Delete an extra

Removes the extra and returns a deletion receipt: a snapshot of exactly what was removed, so the caller can verify and report the change. An extra anything still references is refused with a 409 `resource_in_use` listing the referencing rows — saved presets that answered it — and references are never silently cleared. Requires `customisers:write` and an `Idempotency-Key`; retrying the same request and key replays the original receipt after the row is gone. The delete clears the customiser's cached storefront configuration and runs the advisory language sync, and never regenerates Shopify products, product images, or the product cache.
