feat: Migrate from react-router-dom to TanStack Router v1 - Replaced `react-router-dom` with `@tanstack/react-router` v1, transitioning to a static route tree with composable HOC guards. - Deleted legacy routing components: `AppRoutes.tsx`, `ProtectedRoute.tsx`, `DashboardRedirect.tsx`. - Introduced new routing structure with `routeTree.tsx` for router singleton and guard application, and `AppRouter.tsx` as a thin wrapper for `RouterProvider`. - Updated `routePaths.tsx` to use `component: ComponentType` and added `guards?: RouteGuard[]` to `RouteDescription`. - Simplified `redirectStorage.ts` to a single session storage key for post-login redirects. - Updated architecture documentation to reflect changes in routing, error handling, and component structure. - Ensured all unit tests across 14 modules were migrated to the new routing structure and passed without TypeScript errors.
