update po files with new train 12 strings

Hi @mathjazz!

Here are our new strings.

There are a few fuzzy strings in this batch. In one of the fuzzy strings, we change an interpolated variable from `service` to `serviceName`. It would be easy enough to simply find/replace all occurrances and remove the fuzzy label from those strings. Would that work or do you have more proper ways of dealing with such changes?
