Comply with TMDB API ToS
## Description

[TMDB API ToS states under section 3 (attribution)](https://www.themoviedb.org/documentation/api/terms-of-use):

> You shall use the TMDb logo to identify your use of the TMDb APIs.
> You shall place the following notice prominently on your application: "This product uses the TMDb API but is not endorsed or certified by TMDb."
> Any use of the TMDb logo in your application shall be less prominent than the logo or mark that primarily describes the application and your use of the TMDb logo shall not imply any endorsement by TMDb.

We should set TMDB logo as the thumbnail for every embed using TMDB, and ensure the footer has the exact text they specify.
