refactor: Code splitting, page templates, and PageHeader consistency

- Lazy load all pages for 24% bundle size reduction (575KB → 436KB)
- Created templates: PageTemplate, ComponentTemplate, WidgetTemplate
- Updated RoomsPage and IPMDashboardPage with PageHeader
- All routes wrapped in Suspense with PageLoader component
- Fixed malformed router.tsx structure
