)
Code's all done and merged. Waiting for a deploy for the endpoint to be active.
It will be:
`/api/v1/json/filters/:id` and will take an optional `key` parameter that will (of course) unlock any non-public/non-system filters belonging to the associated user.
It will return a 404 if the filter ID isn't accessible.
The output will be the same as the existing endpoint except it doesn't have the list of tag names.
