Changed breakpoint width to 1440px

Closes #18542

Revert side nav to full width; remove border under nav; remove tooltips on nav links; stop page content shifting with side nav; put project nav in container

Replace raphael-rails with raphael.js so it can be split from the rest of the JavaScript. The gem isn't maintained anymore anyway. Added a network folder with an application.js including raphael components, since that's the only page using it currently.

Added sidebar
Removed elements not present in design

- Move the `TwoFactorAuthsController`'s `new` action to `show`, since
  the page is not used to create a single "two factor auth" anymore. We
  can have a single 2FA authenticator app, along with any number of U2F
  devices, in any combination, so the page will be accessed after the
  first "two factor auth" is created.
- Add the `u2f` javascript library, which provides an API to the
  browser's U2F implementation.
- Add tests for the JS components
