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.
Upgraded Angular packages and related dependencies to version 20.3.14 and updated several @inquirer and other dependencies. Added new sponsor logos to the assets folder and updated the About page to display them, including changes to constants, HTML, SCSS, TypeScript, and i18n files. Minor style and content adjustments were made to the About page.
Added initial Angular project structure including configuration files (.dockerignore, .editorconfig, .gitignore, angular.json, tsconfig), VS Code workspace settings, and application source files. This sets up the base for development, build, and testing workflows.
