Admin labels on photos surrounding explicit flags

* Add 'admin labels' to photos so an admin can classify a photo as:
  * Not Explicit: e.g. it was flagged by the community but does not
    actually need to be explicit. This option will hide the prompt to
    report the explicit photo again.
  * Force Explicit: if a user is fighting an explicit flag and keeps
    removing it from their photo, the photo can be force marked
    explicit.
* Admin labels appear on the Permalink page and in the edit photo
  settings when viewed as a photo moderator admin.
