Preview the venue's last selected index value before confirming a b′ resolution (reporter only).

GET 
/v1/instrument/resolution/preview/:instrument_id

Advisory operator-confirm aid for index-resolved (b′) binaries: returns the last journaled selected index value (the price component's slot-value journal) and its staleness. The engine derives the authoritative b′ outcome from its own sequenced index state — this preview never re-derives it.
