fix horizontal scrolling for Solves and Scoreboard

[Jacopo]

probably a combo of missing max teamname length + the table cuts right columns and somehow a scrollbar is not shown

[Jacopo]

@bboe do you think we should look into it now? especially for the solves table, seems it just gets cut

[Jacopo]

@bboe : I think I see the issue with the scrollbar: the table gets it, not the page (!) -- so a scrollbar exists, but it's at the very bottom of the entire page. This needs an understanding of the various react / bootstrap / responsive stuff that right now I don't have.

[bboe]

eh, I haven't heard anyone complain. I don't think it's worth fixing.

some hours ago a team put an insanely long name, dropping half the table off the screen -- at least we're a little less ridiculous now
