Untrack Brand
Clear GTB — remove an advertiser from the global refresh registry.
The admin-only kill switch for the paid nightly refresh sweep: stops
future collection without deleting the advertiser or its ad history (see
AdLibraryTrackedAdvertiser’s docstring — this is now its one
non-destructive removal path). Refuses UOB/DOB advertisers with 409
regardless of the census UI’s disabled-button state — a direct API call
must not be able to untrack a brand some tenant actively owns or
discovered. Idempotent: untracking an advertiser that isn’t currently
tracked still returns 204.
