Use a mutex for registry CLI txs in webapp deployment commands (#957)

Part of [Service provider auctions for web deployments](https://www.notion.so/Service-provider-auctions-for-web-deployments-104a6b22d47280dbad51d28aa3a91d75) and #948

- Add a registry mutex decorator over tx methods in `LaconicRegistryClient` wrapper
- Required to allow multiple process to run webapp deployment tooling without running into account sequence errors when sending laconicd txs
