Fix frontend

[ValentinFutterer]

• [x] Make upload form pristine again after uploading (error state persists after uploading) (fixed by redirect?)
• [x] Game overview doesnt show the bottom part
• [x] Make URL copy-able per click
• [x] URL: is currently part of the clickable url
• [x] Add padding to uplaod component and center it more
• [x] Add landing page
• [x] Add some ChatGpt text to dashboard
• [x] Check that title only consists of alphanumeric characters
• [x] Reloading page doesnt work (nginx error)
• [x] Add infoboxes
• [x] Route to landing page correctly
• [x] Dont show toolbar and sidenav when on landing page
• [x] Apparently logout doesnt work (Jonas pls elaborate) (requireHttps needs to be set to false in the AuthConfig)
• [x] Reactivate and fix tests (just remove the tests that dont work, I dont think its an easy fix)
• [x] Delete doesnt send request
• [x] Status/URL only shown when reloading component, "Refresh" doesnt do much
• [x] "Refresh all" calls GET /games/:id for every single game instead of GET /games
• [x] Logout doesnt redirect to landing page
