Aug 2023 Quick Emergency Update

Fixed severs not working and added measures to prevent that from happening again.

Some small changes that I did beforehand and got into this update too:

• Remade some of the old pictures to be more readable(specifically, words from days 1 - 30)
• Made the date and time pickers in the settings page display a numpad keyboard
• users now have to input usernames when registering(for future features)
