Convert wallet RPC client to deserialized types

[Quexington]

This PR converts the return values of the wallet RPC client into the marshal-able types introduced in #17201 . Previously, the client was very ad-hoc in what it returned: sometimes dictionaries, sometimes a specific part of the response deserialized, sometimes nothing. The purpose of standardizing like this is so that the whole of each RPC response is available when you call an RPC from the python client. This is important for upcoming PRs which take advantage of the output transactions that every tx_endpoint now returns.
