Some bugs during demo development

[insipx]

• fix bug where we generated two wallets in methods & gateway context leading to insufficient funds error
• use correct signer wallet in endpoints wallet_address and balance
• add a registry-localnet binary that launches an anvil instance with the registry already deployed. Useful for local testing E2E with libxmtp, without touching Sepolia
• generally add some more logging, especially around gas price use when calling the DIDRegistry contract

Thanks for the cleanup!

It's already merged but would like to point out that registry-localnet could be renamed to localnet because we might add more deployed smart contracts there. otherwise lgtm

I actually gotta do a follow up anyway because i screwed up the DID_REGISTRY address, good callout!
