Plant proxy via setStorage instead of addProxy extrinsic

The proxy filtering test runner used to submit an addProxy extrinsic and produce a block before dispatching the dry-run batch. Replaces that with a direct setStorage write into Proxy.proxies. Saves one block per filtering test (~16 blocks across the polkadot proxy file). Also moves the empty-actions early return ahead of the storage write so we do not pay the setStorage cost when there is nothing to test.
