CB-WP-0011-T01: the inspector shows everything, and a gate says so

The renderer moves out of the play loop into inspect.rs and grows from
24 to 42 of the 43 leaf paths a populated GroundView carries. What it
had been dropping was the whole DARVO state machine, the whole GROUND
practice, the scoring mode, Focus tokens, the discard pile, per-seat
protection, and every part of the outcome except the headline.

The load-bearing half is every_view_field_is_classified, which walks
the serialized view for leaf paths and requires each to be listed as
rendered (with a token the output must contain) or omitted (with a
reason). Paths rather than keys: 'problem' occurs under a DARVO target,
a GROUND choice and a Selection, and a key-set walk would let one of
the three vouch for the other two.

Four M-D1-MUT controls, each red for its stated reason. The
unclassified-field control fired for real on the first run --
players.*.hand, a field the gate's own author had missed.
