Improve the styling of views

When working with Empty in my apps, I have found it quite annoying to work with when it comes to styling.

Annoyances:

• No dark mode present. There is only light and dark packaged. Dark mode is easy to create if you use the text color system color that is dark/light automatically for you.
• Can empty not style by default? Then, the view will simply take what I set in UIAppearance for the widgets? I am not sure if this is possible, but it should be?

I propose the following changes:

• See if it's possible to not style empty at all. Empty will just take the form of UIAppearance. We will need to style with text sizes and weights, but that's it. See if we can do minimal setting and UIAppearance takes care of the rest. I am not sure if this is possible? Is UIAppearance only valid for views you create and not 3rd party views?
• Make the included presents be dark mode happy.

Start by inspecting Empty's styling implementation and included presentations, then investigate how UIAppearance and system colors affect them. Done means agreeing on the styling scope and making the included presentations work with dark mode while preserving the intended UIAppearance behavior.
