feat(01-03): decompose organization.tsx and dashboard.tsx into focused sub-components

- Split organization.tsx (1395 lines) into 12 files: AgentRoster, AgentCreator, AgentEditor, GoalList, GoalCreator, GoalEditor, ProjectList, ProjectCreator, ProjectEditor, OrgChart, helpers, orgTreeLayout
- Split dashboard.tsx (1053 lines) into 11 files: Dashboard, HealthCard, MetricsGrid, ActivityFeed, QuickActions, DepartmentOverview, TaskPipeline, SprintProgress, GoalProgress, KanbanBoard, NeedsAttention
- All sub-component files under 300 lines (max: 239 lines)
- Original files replaced with backward-compatible re-exports
- TypeScript compilation passes
