Duplicate a campaign

Duplicates a campaign, including its ad sets, ads, creatives, and targeting by default (`deepCopy: true`). On Meta, this uses `POST /{campaign-id}/copies`. The copy is created paused by default so callers can review before launching. The platform's duplication is asynchronous from our side; once the copy is created on the platform, we trigger a sync discovery so the new hierarchy shows up in /v1/ads/tree. Set `syncAfter: false` to skip the discovery trigger and poll on your own cadence. Meta-only for now. Other platforms return 501 Not Implemented.
