feat: integrate Tailwind CSS with custom theme and animations

Added Tailwind CSS and tw-animate-css imports to globals.css. Introduced a custom dark variant and an extensive @theme inline block with CSS variables for colors, radii, and animations. Included keyframes for shimmer-slide, spin-around, gradient, shine, and background-position-spin to enable consistent theming and dynamic UI effects across the application.
