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.

+"""Manager role — creating tests from templates.
+
+A manager organizes and validates work rather than executing it, but they
+should still be able to seed a test from the catalog directly (same as a
+red_lead/blue_lead), not just approve/reject what leads submit.
