Add labyrinth maze generator and integrate routes

Introduce a new Labyrinth feature: add LabyrinthComponent (TS/HTML/SCSS) implementing maze generation (Prim's/Kruskal) and visualization using the existing generic grid. Wire the component into RouterConstants and app.routes, and add the algorithm entry to AlgorithmsService. Refactor pathfinding internals: rename Node.previousNode -> Node.linkedNode and update PathfindingService and PathfindingComponent accordingly. Add SharedFunctions.random helpers and replace local random utilities. Rename Conway component files/class to ConwayGolComponent and update template path. Add i18n entries for labyrinth (en/de). Minor housekeeping: bump package version to 1.0.0 and disable @typescript-eslint/prefer-for-of in ESLint config.
