Link homework review entry points to pending filter

Dashboard tiles and the curator CTA pointed to /curator/homework without
a status filter, so the default all-submissions list (newest first)
buried old PENDING items pages deep — 19 June submissions sat unseen
for 6 weeks while the top of the list showed freshly approved work.
