fix(ux): resolve tickets #59 #66 #67 — project feedback and demand summary

#66: Project detail "Open Demands" summary incorrectly counted COMPLETED
demands as open. Fix: add `status !== "COMPLETED"` to the activeDemands
filter in /projects/[id]/page.tsx.

#59/#67: Project creation and edit had two bugs:
1. Both invalidated `project.list` but the page queries `project.listWithCosts`
   — the list never refreshed after a save.
2. Success toasts were either absent (ProjectModal) or mounted inside the
   wizard component that unmounts before the toast finishes.
Fix: correct invalidation key to listWithCosts; add optional onSuccess prop
to both ProjectWizard and ProjectModal; ProjectsClient wires onSuccess to a
persistent SuccessToast rendered outside the modals.
