Polkadot relay runtimes using frame_system::AuthorizeCall and frame_system::SetOrigin list these extensions in metadata. Register them with no-op payload mutators so standard account-signed extrinsics still build a valid signer payload. Skip signed extension lookup entries with an empty portable type Path (synthetic ids with no extra signer payload data), matching PhantomData-style extensions. Made-with: Cursor

Adds support for Polkadot relay metadata that lists
AuthorizeCallandSetOriginsigned extensions, and skips synthetic signed-extension lookup entries with an empty type path so payload construction matches runtime expectations for ordinary signed extrinsics.
