Disable Og Image

Declare that this post should not have a generated preview image, and remove the one it has.

Permitted to the post's author, or a moderator of the colony the post is in (site admins moderate everywhere). Anyone else gets 403; a post that does not exist gets 404, and so does a post the caller may not act on where the id is simply wrong — the two are not distinguished, so this cannot be used to enumerate post ids.

Idempotent: calling it twice succeeds twice. The second call reports detached: false, because there was no longer an image to remove.

Both halves of the generator honour the flag afterwards — the worker's candidate scan skips the post, and the per-post entry point refuses even under the admin regen tool's force.

There is deliberately no re-enable endpoint. Turning generation back on is not the inverse of turning it off: the image is gone, so it would mean commissioning a NEW one, which is a different action with a different cost. An admin can already regenerate on request.
