feat(static/css): update tailwind CSS configuration and remove deprecated styles
- **New Features**
- Added **`--container-2xl`** container size variable for wider layout support.
- Introduced **`--text-lg`** and **`--text-lg--line-height`** variables for larger text sizing.
- Added **`--radius-xl`** borderRadius variable for extended styling options.
- **Enhancements & Refinements**
- Removed deprecated color variables (`--color-indigo-*`, `--color-gray-*`) to streamline theme configuration.
- Cleaned up utility classes by removing unused components (`collapse-arrow`, `collapse-plus`, `dropdown`, `toast`, `checkbox`, `radio`, `rating`, `navbar`, `stats`, `filter`).
- Improved spacing utilities with new margin and padding variants (`mt-1`, `mt-1.5`, `mt-5`, `space-x-2`, `gap-y-2`).
- Added responsive variants for better mobile adaptation (`max-md:mt-2`, `max-md:h-8`, `sm:mt-8`).
- **Bug Fixes**
- Fixed positioning utilities by adding missing **`relative`** class.
- Corrected hover behavior for underline styles with **`hover:underline`** replacement.
