Related guides on a page always match the language you selected

When you read a Mita or other entry page, its featured in guides now appear only in the language you chose. A Russian page shows the Russian version of a guide, and its links lead back to the Russian entry.

If a guide has no version in your language yet, such as on a Polish or Arabic page, the card is left out rather than dropping you into an English article, and an empty section is hidden too. The original English and Russian guide addresses still open directly, and Back and Forward keep your place.

The related cards on entry pages were also tidied so they line up evenly at every screen width.
