fixed optimization and UI errors (and not ill anymore)

So i fixed many Issues regarding the performance of the website

Performance (Optimization)

• videos don’t get loaded instantly anymore (180ms cooldown)
• Search is done in memmory atribut caches and requestAnimationFrame.
• all countdown intervalls have been put into one.
• background image is done locally instead of GitHub
• Offscreen Cards now use content-visibility:auto.
• Database and Queries: SQLite changed to 64MB Cahe.
• made 10 indizes for Foreign Keys/Filter.
• Even the translator doesn’t wanna tell me what this means in English. You have to find out yourself.

UI and Interaction errors

• js doesnt crash when pressing a button without being logged in (don’t ask how that happend)
• guest cart can now delete a game from their carts.
• when checking out and not being logged in you get forwarded to login. Didn’t actually happen before.
• Wishlist and card buttons now syncronize when a game is there two times or even more on the front page. It pissed me off before.
• collection badge gets added after animation.

Thats all I wanna write for today
