Add juror quick actions to Members section, redistribute button, dropout emails, and transfer duplicate detection

- Add mail/transfer/reshuffle/redistribute icons to each juror row in Members card
- New redistributeJurorAssignments procedure: reassign all pending projects without dropping juror from group
- New DROPOUT_REASSIGNED email template with project names, deadline, and dropped juror context
- Update reassignDroppedJuror to send per-juror DROPOUT_REASSIGNED emails instead of generic BATCH_ASSIGNED
- Transfer dialog now shows all candidates with "Already assigned" / "At cap" labels instead of hiding them
- SQL script for prod DB insertion of new notification setting without seeding
