fix(kanban): responsive layout, drag-drop offset, and project view enhancements

Kanban pipeline board:
- Fix h-full flex-col layout so board fills viewport height on all screen sizes
- KanbanColumn drop zone: flex-1 min-h-0 so it expands to fill full column height
- KanbanCard: extract KanbanCardDisplay as named export for DragOverlay rendering above overflow containers
- KanbanPage: lift DndContext to page root; add "Add Stage" shortcut to page header
- PageTransition: remove slide-in-from-bottom-4 transform — the CSS transform ancestor was creating a containing block for position:fixed DragOverlay, causing drag ghost to render at a viewport offset
- Migrate fireCampaignToast to toast.custom() Sonner v2 API with explicit card styling

Project & lead views:
- LeadProjectPage: enrich project detail with richer info sections aligned with project stage
- OwnerProjectDetail: expand construction project detail with additional data panels
- OwnerProjectList: project list view improvements
- mockStore: extend lead/project data to support richer project detail rendering
