Finns know that phrase. Just like Americans know the words "your majesty" despite not having any royals.

Finns use it exactly in same way as American would say "your majesty". It would likely be a sarcastic remark coming from a Finn. So the meaning is not that far off.

Yeah, but even then I assume they would want a deeper translation that made the scene more natural to Finns -- where the Moff wouldn't say something that looks like small talk, nor have Vader recognize something as being "pleasantries". Like, have the Moff immediately get to giving status reports, and then have Vader respond with disbelief and say he's behind schedule.
