Merge bitcoin#26131: log: log RPC port on startup

9d14f27 log: log RPC port on startup (James O'Beirne)

Pull request description:

  I just spent a few hours trying to figure out why "18444" wasn't getting me to regtest's RPC server. I'm not the sharpest tool in the shed, but I was maybe understandably confused because "Bound to 127.0.0.1:18445" appears in the logs, which I assumed was the P2P port.

  This change logs the RPC listening address by default on startup, which seems like a basic piece of information that shouldn't be buried under `-debug`.
