View calls on chainCall Workflow
This diagram shows the call execution flow: starting with sudo_set_network_rate_limit, passing through validation
(signature, nonce, mortality, fee payment), then pre-dispatch checks where it may fail with errors like NetworkDoesNotExist, followed by dispatch and modifies storage: SubtensorModule.NetworkRateLimit, and finally post-dispatch where ExtrinsicSuccess is emitted and fees are settled.
