feat(manager): allow manager to create auto-approved campaigns and tests from templates

A manager organizes and validates work, so their own campaigns skip the
draft -> submit -> pending_approval queue and go straight to active with
the start_date they provide (they're the same role that would otherwise
approve it). Manager can also now create tests from the catalog, same as
red_lead/blue_lead.
