Add section IDs and smooth scrolling for improved navigation:

- Updated components (`Hero`, `Welcome`, `EventsGrid`, `ImageCarousel`, `Drinks`) to accept optional `id` props and applied them to `<section>` elements.
- Enabled smooth scrolling by adding `scroll-behavior: smooth` to global styles.
- Enhanced dropdown menu: added internal links for section navigation and adjusted styling for improved responsiveness.
- Updated color handling in `ImageCarousel` to use CSS variables for better theme consistency.
