fix: resolve CSS cascade issue with UI components and Tailwind utilities

- Move UI component styles to @layer components in tailwind.scss
- Remove ui.scss and integrate imports directly into component layer
- Add SCSS files to Tailwind content config to prevent CSS class purging
- Update Angular project configuration to remove ui.scss references
- Ensure Tailwind utilities can override component styles properly
