Switch route definitions to lazy-load components via loadComponent dynamic imports and remove direct component references from RouterConstants. Remove several components' standalone flags and adjust component metadata (styleUrl vs styleUrls) and imports accordingly. Make AlgorithmsService and AlgorithmsComponent synchronous (getCategories() now returns an array and template iterates categories directly). Replace alert in PathfindingComponent with MatSnackBar and inject it. Simplify LanguageService initialization to use existing translate configuration. Remove unused ReloadService. Make GenericGridComponent.lastCell protected. Miscellaneous tidy-ups across related files.
