Pull Request Overview

This PR refactors the dependency structure for Tailwind CSS and related PostCSS packages by moving them from devDependencies to dependencies in the ui-components package. The change suggests these packages are now required at runtime rather than just during development/build time.

Key Changes

• Moved @tailwindcss/postcss, postcss-calc, and tailwindcss from devDependencies to dependencies
• Updated tailwindcss to use catalog versioning for consistency with other dependencies

Files not reviewed (1)

• pnpm-lock.yaml: Language not supported
