Drop `position` from the `asset_usages` unique constraint so the same asset can't be attached to one target/slot more than once, and update the insert's onConflict target + lookup to match the narrower key. Guard it at the service layer too: attachAssetService now rejects an attach when the asset already has a usage for that target with a new ASSET_ALREADY_ATTACHED (409) error, backed by an assetUsageExistsForTarget query.
