Adjust the design to fit nc30

[szaimen]

See https://github.com/nextcloud/server/issues/46016

Final is scheduled for 2024-09-14, so should be ready for end of august in best case

• [x] The backgrounds are in the "Compressed" folder at https://cloud.nextcloud.com/f/9996388
• [x] Indeed the main border container can be adjusted to var(--body-container-radius), 12px because it’s calc(var(--default-grid-baseline) * 3)
• [x] Buttons, input fields and entries are var(--border-radius-element) which is 8px
• [x] The sizes of the input field and button might have to be adjusted, new heights are 34px (--default-clickable-area)

Nice, looks very cool! :) The buttons are a bit different than in the main web interface, right? Brighter with possible contrast issue, and have a border around them.
