"""Sync one campaign into the real ad account, then delete it.

Opt-in: set MASKANX_LIVE_TESTS=1. Every object is created PAUSED, so the
test cannot spend money, and the objects are deleted in a finally block
so the account is left as it was found.

This exists because the unit tests all run against a fake transport. They
prove the code sends what we think it sends; only this proves Meta accepts
it and that what lands in the account is paused.
