Minor enhancement of coordinator log messages

[Denchick]

How It was:

{"level":"info","ssl":true,"time":"2024-12-26T12:33:10Z","message":"init client connection"}
{"level":"info","user":"spqr-console","db":"spqr-console","time":"2024-12-26T12:33:10Z","message":"initialized client connection"}

How it became:

{"level":"info","ssl":true,"time":"2024-12-26T12:33:10Z","message":"init client connection"}
{"level":"info","user":"spqr-console","db":"spqr-console", "ssl":true, "time":"2024-12-26T12:33:10Z","message":"init client connection OK"}
