Fix _print_value_fmt for some objectives and fix some latex labels

[YigitElma]

#1189 changed the format of _print_value_fmt some recent merged PR's added new objectives that shouldn't work with the new format and throw IndexError: Replacement index 2 out of range for positional args tuple.

Also, I think I missed one of the objectives during that PR. This fixes the formats.

And some small label fixes.

Can you also fix <|B|>_axis and B_phi|r,t latex labels in this pr?

Are these all the objectives in the current master where the formatting specification is used after _print_value_fmt?

I searched _print_value_fmt = on VS Code and checked the strings. These should be all of them, unless a PR gets merged without checking the print.

What is this exactly? You can add your commit here if it is a quick fix
