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.
