website: the sidebar button fits when the apps group is open

On /alkalmazasok the Alkalmazasok group renders expanded, which gives the sidebar
a 16px scrollbar and narrows it from 239 to 224. At .95rem the Hungarian label
wrapped to two lines there (the English one still fitted, which is why it showed
on one page and not its twin). Sized to the narrow case, measured not guessed.
