Feature summary:
Create a server side Denylist of Wikidata Ids that should not be used for depict statements on Commons, e.g. ["Q123", "Q345", "Q678"].
For this initial version, we should just manually copy the MachineVision denylist.
Whenever a user tries to add depict statements, the server should check each Wikidata item to see if it's included in the denylist. If it is, the edit should not NOT be saved to Commons.
NOTE: For this first simple version, the end user will not get any notification that a depict statement was rejected. Another task will be added shortly to handle sending messages back to the client.
Benefits (why should this be implemented?):
This helps improve the quality of contributions using the ISA tool.
It will also serve as a basic framework for experimenting with more in depth rules, which could run on a schedule and be combined with our manually populated denylist.
