feat(KB-618): add multi-project support to dashboard

- Add project API methods and types (fetchProjects, registerProject, fetchProjectHealth, etc.) - Add ProjectCard component with health metrics, status badges, and pause/resume actions - Add server-side project management routes for multi-project orchestration - Add ActivityFeed component with grouped entries and project badges - Add SetupWizard component with 5-step project creation flow - Fix TypeScript errors in server routes for listProjects and getGlobalConcurrencyState
