Sweep found pitch slug was the one content-tool free-text field still outside
the anti-soup guard (a product could be slugged 'wip'/'asdf'). Add it to the
guard (min 2, so real short slugs like 'ui' pass). Also fix two pitch tests
that were false-passing on a 1-char title (the title guard rejected first):
give them substantive fields so they actually exercise the role gate
(not_authorized) and the non-cell-target rejection (invalid_state).
