Introduce Bubble, Quick and Heap Sort documentation: add wiki URL constants, update sorting component to show Bubble/Quick/Heap Sort explanations with Wikipedia links, and include additional disclaimer text and list in the UI. Add corresponding i18n entries in English and German containing algorithm descriptions, note/title and several disclaimer lines.
Replace plain container with Angular Material mat-card in pathfinding view and reorganize UI: add mat-card header/content, algorithm explanation block, control buttons, node-type toggle group, grid-size inputs, legend and results display (path length & execution time). Import and wire MatCard modules in the pathfinding component. Move .algo-info styling from the component SCSS into global styles.scss and remove it from the component stylesheet. Update sorting template to use new SORTING translation keys and add an UrlConstants reference in the sorting component TS for external links. Add/adjust i18n keys in en.json and de.json for sorting and grid labels to match the updated templates.
Refactor sorting to produce and consume SortSnapshot sequences for visualization. SortingService now creates immutable snapshots and implements bubble, quick and heap sorts (with helper methods) instead of performing UI delays; a swap/heapify/partition flow records state changes. SortingComponent was updated to animate snapshots (with start/stop timeout handling), added array size input and controls, stores an unsorted copy for resets, and uses ChangeDetectorRef for updates. Minor UI tweaks: faster bar transitions, info color, updated default array size and animation speed, and added i18n keys for ARRAY_SIZE (en/de).
