Fix dim read posts setting not being applied for card view

[hjiangsu]

Pull Request Description

This PR fixes an issue where disabling "Dim Read Posts" was not being respected when using card view. Additionally, I've applied a bit more margin between each metadata widget to improve general readability.

Note: In #1510, I removed the spacing: 8.0 from the Wrap widget, and moved the spacing to the margins of each metadata widget. However, I only applied a margin of EdgeInsets.only(right: 4.0) when it should've been EdgeInsets.only(right: 8.0) to keep the same spacing.

LGTM!

BTW, it's not related to these changes, but does the new combined up/down arrow and vote count change in response to being dimmed, even when colored to indicate a vote? I couldn't tell but it kinda looked like it didn't.

I believe so? It's a bit hard to see due to compression, but both the card/compact views share the same logic so it should be applied!
