Floating links in Save postbox

[sabernhardt]

When on smaller screens, links for "Uploaded by" and "Uploaded to" float to the opposite side of the text.

	.misc-pub-section > a {
		float: right;
		font-size: 16px;
	}

See #54811 for related issue. Probably can solve in a single patch.

Floating the links on mobile started with r26134 (25858.responsive.diff)

This looks good. It also has a small accessibility benefit, since correlating the left side / right side lay out for users with low vision at high zoom could be a problem. I'm not sure why this was ever aligned differently from on desktop; but I don't think it is any benefit. Marking for commit.

In 53115:

Media: Align username and post title in Save postbox.

Remove the float alignment that places the "Uploaded by" username and the "Uploaded to" post title on the opposite side of the Save postbox for mobile. This matches the alignment on desktop, and makes it easier for low-vision users to track the information relationship between label and content.

Props sabernhardt.
Fixes #55508.
