Fix mobile spacing for draft board and dashboard layout (#13, #329) (#404)

Reduce double-stacked padding on draft board page from 64px to 32px on
mobile by using responsive p-2/px-2 md:p-4/md:px-4 classes.

Replace dashboard CSS grid with flex layout so My Leagues and Create
League stack naturally at the top without being stretched apart by the
row-span-2 events column. Mobile order preserved: My Leagues, Events,
Create League.
