Extract RPC push logic into `@tx_endpoint` wrapper

[Quexington]

Recreation of #16859 @ main (includes also #16865 which has already been cherry-picked to main)

This change takes the responsibility for pushing transactions off of the individual RPC implementations and extracts it to the @tx_endpoint wrapper which reads from the "transactions" key of the response to push the transactions to the wallet automatically if requested by the RPC caller.

Repeating what the initial PR said, the main part of this change is easier to review if you hide whitespace.
