fix(neon,neon_files,neon_news,neon_notes): Fix notch clipping content

[provokateurin]

Fixes #294
I tested with both the normal drawer and the always visible one and both work with this in portrait and landscape mode.

This does not fix the issue for other pages like the settings or the file info where it's fairly noticeable

[provokateurin]

Ah I only fixed it for the main page because of the screenshot in the issue. I'll look into the other pages as well.

I'm not sure it'll work but maybe we can just wrap the entire material app with a safe area 🤔

[provokateurin]

The problem is that then the status bar will be just black. We can do it, but apps usually don't do it.

[Leptopoda]

Thinking about it some clients might want to display something full screen.
Like the video feed of talk in a call.

Maybe we can create a custom go_route like SafeAreaRoute that wraps the given page in a safe area?

[provokateurin]

For other pages than those displayed in home we need to individually add the SafeArea. In Talk for example the call is on a new page that isn't rendered inside the home page, so there it wouldn't matter. I think we can just add the SafeArea to all the pages that need it and then we are good.

@Leptopoda Please review again

We should've done this earlier.
Such an easy fix xD

Thanks.
