Flatten the Paper development hierarchy

[pontaoski]

This makes the content more immediately accessible and easier to browse through. Styling has also been adjusted as necessary to accomodate a flatter hierarchy of items; presenting content as a list with headers instead of a grid of cards.

ATM, the hierarchy of other stuff isn't flattened; I can do that if y'all like how it looks on the Paper dev pages.

In addition to the Doc Cards being weird on main admin/dev/contrib pages, I find it weird that the "Welcome to the paper docs" at the top of sidebars have a doc icon as well. Overall, I am a fan of the style though! thanks

Could this be updated? If you are not able to, do not worry.

Approved from a technical and feature POV. Help wanted for if this is better than the current sidebar

Looks good. I still want to do the thing where the "Development", "Admin" things are on the top of the page and you change between projects by the logo/project name however.

But this still works with that, making the whole sidebar just development

I'm not sure if the sidebar icons add any value to the navigation experience, it just seems like visual clutter to me; maybe make them a little smaller and darker (to make the page/section names stand out more)?

visual bug when page names are wrapped (icons are shrunk)

light mode makes the sidebar icons blend in with the background completely
