Inputs border to main bg and fix white inputs

[skjnldsv]

During the variable pr, the white radio/checkboxes have been broken.
They need to be base on the white colour only, and not relative to the text colour or bg colour.

Therefore, this is fixed.

On the other hand, the border & bg of the inputs needs to be based on the main background colour, not the text. This will ensure a better contrast! :)

Bump? 😭

@skjnldsv Maybe you can add some variables for the border color values? Otherwise it will get messy to maintain those different transparency levels used.

The rest looks good 👍

Hum, it's not supposed to be edited. But it doesn't hurt I guess! :)

[skjnldsv]

@juliushaertl Done ;)
I don't want to add this to the variable.scss since it's not supposed to be changeable. It's just to be easier to understand.

@nextcloud/designers the drone fails but not because of this :)
