Backend register for event via credit card has problematic pre-help text and should be completely removed and replaced with only a translation-friendly indicator of live vs test

I think the tpl line needs to be completely replaced. I would remove the first sentence since it adds no value since right above it already says the name when it's present, and when it's not present is the cause of this notice, and then the second sentence is not correct in other languages (the "live"/"test" is always in english). Elsewhere the approach for that when there's a known list of values is to just hardcode the full sentences in an {if}
block.
I do think it's important to identify if it's live or test, but since none of the above has been raised as an issue the help text itself seems very unimportant. Maybe it should just have some kind of icon indicating live or test and that's it.
