Pure black theme UI quirks

[codenyte]

Bug Description

There are multiple problem with the Pure black theme, but I'll report as one issue. Thankfully some will already get fixed in PR #1347.

There are multiple issues with the top app bar, I'm not sure if this is the expected behavior but it has a grey-ish color while the rest of the app background is black. One example of this is the settings page:

Either the search bar needs more padding at the top or the top app bar needs to have the grey background removed.

Another issue with the top app bar occurs on the Feed page when "Hide Top Bar on Scroll" is enabled:

This could also be fixed by just removing the grey background, or by keeping it and also applying it to the notification/status bar (as it is the case when "Hide Top Bar on Scroll" is disabled).

Some sections of the app like "Explore instance" or "Create Comment'"don't use the black theme at all, even if it is enabled:

Steps to Reproduce

1. Select Pure black theme
2. Go to the aforementioned areas of the app

Probably not that relevant, but the About -> Licenses screen doesn't use the pure black theme either:

The Account settings page also looks pretty weird

Account settings will be fixed by my PR.

I'll eventually look at the rest as well, and any cases I find in my everyday use as well.

Oh I'm sorry I didn't realize that this was included in your PR
