dark mode support for logo, text and background for guest pages
There is issue with logo in guest.css as it used static path of logo, which prevents changing logo between light/dark mode. So I had to change it to eCloudTheme
Main MR: https://gitlab.e.foundation/e/infra/ecloud/nextcloud-apps/ecloud-theme-helper/-/merge_requests/171
as dark mode murena logo is pure white (e is only orange) , for other pages, it becomes invisible in dark mode (dark mode has issue in all guest pages, issue is created); so I had to use var for background theme as well.
So so many changes, but I had to do it here only; cant make more changes in ecloud-theme-helper. So can you please review both.
Everything is deployed to staging (murenatest.io) , so you can check/test there.
