fix: no legend message

[Grammostola]

Aims to fix #1858

[Grammostola]

I was thinking two things here in order to more solidly fix the no legend message.
First, what with the recent PR to change "Legend" to "Teckenförklaring" in the Print control, the same reason should apply to the Legend control and the "No legend" message, no?

If so then

which looks like the message did prior in that it is slightly clipped. Change the padding class or perhaps change the text size rather as the text seems a bit large at present. Making it slightly smaller makes it as large as the layer title. Therefore I propose making it slightly smaller still:

This is currently what the pr looks like.
