Add COI/manual reassignment emails, confirmation dialog, and smart juror selection

- Add COI_REASSIGNED and MANUAL_REASSIGNED notification types with distinct
  email templates, icons, and priorities
- COI declaration dialog now shows a confirmation step warning that the
  project will be reassigned before submitting
- reassignAfterCOI now checks historical assignments (all rounds, audit logs)
  to never assign the same project to a juror twice, and prefers jurors with
  incomplete evaluations over those who have finished all their work
- Admin transfer (transferAssignments) sends per-juror MANUAL_REASSIGNED
  notifications with actual project names instead of generic batch emails
- docker-entrypoint syncs notification settings on every deploy via upsert
