UX: login modal adjustments (PR #12552)

Some adjustments based on feedback from @CvX :heart:

  1. add focus styles to social logins (I also adjusted the hover styles a bit)

  2. Use sentence case, not title case

  3. remove the slidein animation on login/signup modals… it’s had a good run, but it messes with browser autocomplete plugins like 1password. It’s not worth adding more complexity for some one-off visual flair, especially considering we want to eliminate the modal in the not-so-distant future.
