24-hour read as 13.45 in Denmark, because that is how Danish writes a
clock and toLocaleTimeString was doing as it was told. But somebody who
leaves "follow the region" and picks 24-hour has just said they want the
region to stop deciding — and they mean 13:45.
So the two explicit modes build the string from formatToParts and pin the
mark between the hour and the minute. Only that one literal is replaced:
everything else stays the locale's, which is why Japanese keeps 午後 in
front of it and English keeps its lowercase pm after. 12-hour got the
same for free — it had the identical 01.45 pm.
Auto is left alone. A setting that says to follow the region has no
business arguing with it.
