feat: specify media type via url path: systemtags-current/$mediaType

- only the media part of the mime type can be search, but not the full
  mime type. It can be added, should it become necessary.
- thus fixes previously hardcoded selector for image/ types
- also fixes a return type hint
- adds a return type hint
