Implement Prim and Kruskal maze generation in the Labyrinth component with animated generation and UI guards. Introduces isAnimationRunning signal, mazeAnimationSpeed, maze node order tracking and animateMazeGeneration; createRandom(now takes a boolean) triggers either Prim or Kruskal flow, sets random start/end, and animates. Refactor Node.distance -> nodeData across models, components and the PathfindingService (Dijkstra/A*) to use nodeData for g-scores/ids. Add SharedFunctions.shuffleArray utility and update i18n (EN/DE) with labels for Prim/Kruskal. Misc: minor cleanup/init changes and drawing logic adjustments to support the new maze flows.
