Catch Phpstan Up

Its last few updates have been irksome. I need to eliminate more of the new problems with annotations rather than code because I can't figure out what it's objecting to. Nevertheless, it provides a very valuable service, so ...

Its latest release is flagging calling abs with a string, even when the string is defined as numeric-string in a doc block. Php generally allows it, though not with strict types. Changed to add 0 in those situations.
