[Stats Refresh] Post Stats: fix Post Title display issues

[ScoutHarris]

Fixes #11618

This addresses the problems noted in #11618 regarding the Post Title displayed in the title card, namely:

• The Post Title is now dark grey
• The font is NotoSerif-Bold
• The spacing between the Showing stats for label and the Post Title is now consistent regardless of the post title length.

The problems stemmed from this change, where I got...creative, and made the Post Title look like that on Latest Post Summary since it's now clickable.

The fix was simply to remove the postTitleLabel.attributedText, thus allowing the original formatting to shine through.

To test:

• Go to Post Stats, and verify the three points noted above.

Looks good!

Can you double check the spacing between the labels when there's 1/2 lines. In the screenshots above it looks like there's around a 2pt different in spacing between the two.

Hey @SylvesterWilmott .

Can you double check the spacing between the labels when there's 1/2 lines. In the screenshots above it looks like there's around a 2pt different in spacing between the two.

The space between the labels is 2pts. However, the one line Post Title label is a bit spacious -

Not sure why, but I've created #11637 to look at it.
