Fix MWPW-133351

Dscription
A couple things were changed last minute during the release. Some of these changes caused a low-exposure regression on the CKG pill. There's the quick fix for it.

Fixes includes:

• If existing SEO pages are found, they should be prepended (prioritized)
• If no translated name found for non-EN search pages, hide the pill.
