Display the “verified account” trophy on the inbox page

The Lichess account is used to send surveys to users (#20404). Due to the ubiquity of phishing attacks asking users to click on links, it is a good idea to display the “verified account” trophy on the inbox page, so that the survey participants can rest assured that this is an official account and nothing phishy is going on.

The trophy can be shown at the right end of the header (keeping in line with the placement on the profile page):

I highlighted this to our Moderation and Community Coordinators to get their view. They opined that there's no reason this should go beyond the Lichess account.

The ✔️ symbol is also on the profiles of a few high-profile individuals.
These individuals aren't necessarily direct members of the Lichess team. In the words of the mod coordinator, the marker does not equate to Official.

Therefore:

• So not to imply the words of a third party are representing Lichess, and
• To prevent abuse.

It may be better to limit this marker to just the Lichess account.
