Walkthrough

The project upgraded Angular, NgRx, TypeScript, Vitest, Tailwind, RxJS, and related dependencies. It added OpenNG Optimus UI packages and build-script allowlisting. PrimeNG providers, components, services, icons, themes, and Tailwind integration were replaced with Optimus UI equivalents. TypeScript root directories and path aliases were updated.
