This PR optimizes the codebase for performance by focusing on bundle size reduction and improved load times.

Key changes include:

• Dependency Pruning: Removed unused client dependencies (e.g., PrismJS, Marked, FlexLayout, Ionic, various Material modules) and unnecessary lifecycle scripts to reduce install size and initial bundles.
• Lazy Loading: Implemented lazy loading for the login module, ensuring Firebase Auth/Analytics are only loaded when the login route is visited, thereby improving initial application load performance.
• CSS-based Layout: Replaced @angular/flex-layout with lightweight CSS for toast messages, removing a runtime dependency and streamlining layout logic.

These changes aim to deliver a leaner and faster application experience.
