Improve .mayoral-box UI

This commit does a couple atomic things, like all good commits from lazy
engineers who know better:

* Moves JS to bottom of <body>
* Removes assets/js/main.js, which didn't appear to be doing anything
* Removes database config comments in favor of the .env file to use with
  foreman
* The thing the commit title says (makes the whole mayoral-box
  clickable, and have some stats below each of them)
