fix(campaigns): make Expected Detection editable when adding a test to a campaign

Was a read-only reference shown only when the template already had
content, unlike the standalone create-from-template form where it's
an editable field feeding detect_procedure on the new test. Brought
the campaign flow in line with that so leads get the same editing
capability regardless of whether the test is going into a campaign.
