Deleted the particles background component and its related files. Updated routing logic and constants, refactored topbar and algorithms pages, and performed dependency updates and cleanup in package files. Also improved i18n translations and adjusted TypeScript configuration.
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.
