[mod] openverse - use of internal APIs and addition result fields (#6701)

Additional fields:
  add resolution, thumbnail and author to the image result

Types:
  use EngineResults and add type hints from internall APIs

Disabled engine:
  as of 09/2026: The availability of https://openverse.org/ is poor, and queries
  and image requests often time out. However, these issues also occur when using
  a WEB browser to search on openverse.org or view images.
