turn views into tabviews

Toon testing:

• works
• (also a FIXME comment in the code): the tab bar is a real waste of space when there's just one tab
• the apexcard does not deal well with the smaller space, and also ends up with the wrong font suddenly?!

the apexcard does not deal well with the smaller space, and also ends up with the wrong font suddenly?!

the font change does appear to actually be this PRs fault and in fact almost everything has the wrong font now. I wonder if this is an LVGL bug

in fact almost everything has the wrong font now.

fixed/worked around now

Sun Next midnight moving into the next column there is weird. Goes with what I saw on apexcard, like something is keeping an area empty above the logbox.

fixed

this also fixes apexcard (which now is too big but it had scaling issues before this PR)

marked as draft as I decided to put more work into this PR (sections inside a view now turn into columns, which means finally turning a lot of fixed pixel sizes into dynamic things)

[Habbie]

This is turning into a bigger UI rework.

Current state:

something happened to the sides of the light buttons. Also the brightness slider is now getting quite small due to the top bar (and the logbox, which should become foldable)

The clock really is too far in the corner on the Toon screen with the bezel.

(and the logbox, which should become foldable)

or just go. Maybe we'll find something else for the bottom at some point. Or not.
