Initial implementation of ASD Dashboard with customizable boards, views and widgets

[kwuite]

This is the first major PR to the main branch, introducing the core implementation of the ASD-dashboard project. This project is designed as a Progressive Web App (PWA) to facilitate ⚡ Accelerated Software Development and 🚀 Automated Service Deployment through a dynamic, widget-based dashboard.

Key Features:

• Boards and Views: Allows users to create and manage multiple boards, each containing several views. Views help organize widgets into distinct configurations for easy navigation and customization.
• Widgets: Each widget is an iframe that can load external services or APIs. Widgets are resizable, movable, and their state (size and position) is persistently stored in localStorage.
• Responsive Design: The dashboard uses CSS Grid to provide a flexible, responsive layout that adapts to various screen sizes, including support for wide and ultra-wide monitors.
• Configuration: The dashboard can be configured via a config.json file, which includes settings like widget positions, auto-refresh intervals, and service URLs. The configuration can be loaded from local or remote sources.
• LocalStorage Integration: Stores user preferences and widget states, allowing for persistent sessions across page reloads.
• Service Worker: Enables offline functionality, caching essential resources, and enhancing the app's performance as a PWA.
• Custom Logger: Introduced a logger for enhanced debugging capabilities without cluttering the production console.
• Testing with Playwright: Automated UI tests have been implemented using Playwright, ensuring stability across key features. Continuous integration is set up via GitHub Actions.

Other Changes:

• UI Improvements: Implemented a polished UI with draggable, resizable widgets. Features like fullscreen toggling, dynamic grid resizing, and menu management for widgets have been added for better user experience.
• Initial PWA Setup: The core structure of the dashboard as a PWA, including service worker integration for offline capabilities.
• File Structure: Organized the project into a clear structure, moving files to a dedicated src directory for better maintainability.

This PR sets the foundation for the ASD-dashboard project, introducing the essential features and core architecture for future development. It's the first complete implementation that can be used for the core ASD project purpose.
