### DELETE /streaming/account/{accountId}/source/{sourceId} (remove a configured source)

### Frozen Marge route: removes the source from every device of the account
### (HandleMargeDeleteSource), mirroring the account-level POST add-source.
### Idempotent — a 200 is returned whether or not the source was present, so this
### pins the route + contract without depending on prior state.
