Count the Advanced CHOAM Auditor in the expected Traitor deck

tools/sample-custody.ts built its expected Traitor deck from the printed
leaders only, but Advanced CHOAM adds its printed extra Auditor disc during
setup, so every fresh Advanced all-expansion sample failed at setup with
'physical traitor custody'. The expectation now includes the Auditor for
Advanced CHOAM seats; the resumed saved positions were unaffected because the
resume path recomputes the inventory from the game.

With the fix a fresh --profile combined-homeworld-nexus --rules both --players
all run completes 2/4 (both Advanced). The two Basic samples stop at phase 6
on 'Odd-force Basic Occupy awaits the preserved publisher casualty-rounding
ruling', one of the three other unresolved questions recorded in the capture
resumption note, not on the five implemented rulings.

tests/sample-custody.test.ts (11 cases) and the faction-games suite pass;
types and lint are green.
