Improve: Increase the hitbox area of Search box on mobile devices

[ShadowArcanist]

At the moment on mobile devices the search box only trigger the search feature if we tap on the search icon (shown in orange box in the below image).

Make the hitbox cover the entire search box (shown in red box in the below image)

Additionally, the text "Search" is missing on the search box.

Additionally (again), add some more space below the search box and the first accordion (there is a high chance of people accidentally clicking the search box now)

There is a complication, the search input in the sidebar menu on mobile is actually a button. It has no input field like the default search input field (on screenshot below). I will have to swap this out.

If we horizontally shrink the browser, we also lose the dark mode switch for some reason. Might be a internal responsive css class doing that with media queries. Will look into that. I removed the border that gave the illusion it was a input field. That button toggles a new search field at the top of the screen, might need to look into what we want to do with that and how far we can customize that.

Update: on mobile its just a button by default, this needs to be swapped. Will look into it!
