Landing page & auth

• Added a landing page for non logged in users to learn more about the app
• The hero section has a title, description, and two call to action buttons for logging in and reading more information
• There are also a few sections on the landing page that just display placeholder images and text for now since the app doesn’t actually exist yet
• Added an animated faq component at the bottom that’s a collapsible accordion
• Added a login page with a form where you can either sign up, sign in with email/password, or sign in with OAuth providers (Google and GitHub coming soon)
• Added a navigation bar on the landing page
