Task 3 of #583. New DashboardView at /dashboard composes the approved layout:
done-recently strip, Active-now project panels (project -> active milestones ->
open tasks, in-progress flagged, + no-milestone group), and a rail with
upcoming events / week stats / quick-create (Task/Note/Process). '/' now
redirects to /dashboard; AppHeader gains a Dashboard link and relabels
Knowledge -> Browse (route unchanged). Empty + loading states included.
