Add login button

[galactic-magpie]

Closes #

💸 TL;DR

• Adds a 'login' button to the logged out win page
• Updates devvit dependencies to 0.12.22.next in order to use the login effect
• Fixes a bug with logged out play: when the logged out user wins and logs in to 'save' that win, the game shows "Nice try" until the user refreshes the page again. It still briefly flashes (I'm looking into why) but automatically updates to the win page without needing additional page refresh.
