What Was Accomplished

• Updated JS and PHP in REST API block so the daily horoscope links can be displayed in the network layout.
• Updated the CSS to vertically center the zodiac signs without inline-flex ( which creates empty space at the bottom ).

How It Was Tested

• [x] Local
• [x] Remote

How To Test

• [x] Horoscope links appear in content using the Network layout. They are always visible in the editor, but only present in the rendered content when they actually exist.
• [x] Horoscope links still appear as normal in the Daily Horoscope layout.
• [x] Network layout without horoscopes works as normal.

@jessica-townsend I'm double pointing out that display_zodiac_links now defaults to false so when this ships to a site we have to go flip the toggle where we want the links to show.
