fix(bounty): derive shortlist selection from live application list

Declining a checked application unmounted its checkbox but left its id in
the checked set, so the sticky-bar count stayed inflated and Approve
shortlist submitted a DECLINED application. Filter the selection against
the current SUBMITTED rows so the count and the payload only ever include
actionable applications.
