UX: Display different content once early voting ends

It's been brought to my attention that several people will show up to an early voting location on election day. If you want to vote on election day, you need to go to your regular polling place, not any early voting one.

Once early voting ends, we should change what's displayed on the site to make it clear that early voting has ended and that you should go to your normal polling place on Tuesday if you haven't voted yet. What content should be displayed at this time?

Additionally, what content should be displayed once one election is over and early voting has not begun for the next one?

Combines with #50 and #51 as a feature

Start by reviewing the requirements in this issue together with the related issues #50 and #51. The work is ready when the content and display behavior are defined for the period after early voting ends and for the interval between elections.
