Reduce initial bundle size via lazy loading

[bracyw]

Changes

Converted all page-level routes from eagerly imported components to lazy-loaded routes using loadComponent with dynamic imports. This splits each page into its own chunk so the browser only downloads code for the current route, cutting the initial bundle size significantly. Also removed ~30 eagerly imported NgModule re-exports (PrimeNG, Angular Material, Forms, etc.) from main.ts that were bundled upfront as dead weight -- standalone components already import what they need individually.

In app-routing.module.ts, all component route definitions were replaced with loadComponent arrow functions and the AppRoutingModule NgModule class was removed in favor of exporting routes directly. In main.ts, switched to provideRouter(routes) for standalone bootstrapping and dropped the bulk importProvidersFrom call. Only BrowserModule and DynamicDialogModule remain as root providers.

Test Cases

• Navigate to each route (/landing, /graph, /map, /charging, /bms, /bms/segment/:id, /faults, /faults/fault-graph, /camera, /commands, /efuses) and confirm the page loads correctly
• Confirm the root redirect (/ -> /landing) still works
• Verify named exports (BmsDebugPageComponent, BmsSegmentViewComponent, CameraPageComponent) resolve correctly via .then((m) => m.ComponentName)
• Check browser DevTools Network tab to confirm chunks are loaded on navigation rather than upfront
