Enhance UI & Fix Broken CSS

Fix existing pull request 404 that is supposed to remove [login to view URL] library and replace it with our system ui to reduce build time. As of now all css is broken as if tailwindcss is not applied and some components are double. We need a fresh, modern look that immediately signals quality and trust worthy of an enterprise headless cms. The brief is focused squarely on visual design—navigation and overall layout will remain as-is—so you can dive straight into aesthetics. What we need • A refined, consistent color scheme applied across our key screens like setup-wizard, dashboard, settings, user, mediagallery etc. • Accessible contrast ratios that meet WCAG 2.1 AA. • A compact style guide detailing the palette, usage rules, and any new color tokens. See docs The interface should feel clean, bold, and current without abandoning our existing layout or forcing any code-level rework. I’ll consider the job complete once the pr 404 will not destroy the exiting Next branch and ui will be enhanced.
