Object-ness comes from the card face, not a parallel list

'This is most certainly an object' (WIZARDBLADE's FAQ) — and the card
data already says so: every physical item bears the OBJECT subtype on
its face. isMovableObject now reads it from there, retiring the
hand-kept list — which had missed MASTER KEY and HANDFUL OF TACKS,
both object-marked. Ungated: no stored ledger holds a swap or drop
this widens (verified against production), and refused commands are
never recorded.
