Remove a contact from an automation without knowing the id of the contactAutomation row that links them, so a caller holding the contact and the automation does not have to look it up first. Remove a contact from an automation takes that row id in the path instead.

The contact is identified by contact_email or contact; when both are sent, contact_email wins. Only an active run is removed, and if the contact entered the automation more than once, the most recent active run is the one removed — repeat the call to remove earlier ones.

Requires permission to edit contacts.
