test: fix e2e teardown to add FREE pricing record after existing ones

The cleanup in make_actor appended a FREE pricing_info with a hardcoded
startedAt='2024-01-01', which the API rejected for actors that already had
later-dated pricing records with "The record you are adding must start after
all existing records." Compute startedAt as max(latest_existing, now) + 1s so
the added record always starts strictly after existing ones.
