PRICE-01 review: spaced-token check passes the length rule; F3 default pinned

The spaced-token check used a 5-character token, which the new 16-character
rule refuses on its own, so a validator that stopped checking spaces passed
(reviewer mutation R06). It now uses a long token and checks the reason.

Also pin F3 with no maintenance_enabled key: the default (off) holds and no
no-price words show (reviewer mutation S04). Tests only.
