Update events, images, and improve layout:

- **Events update**: Replaced existing events with new details and images.
- **Image updates**: Replaced outdated images with optimized ones (e.g., `Event1.png`, `Event2.png`, `Event3.png`).
- **Footer improvements**: Added `id` to enable smooth scrolling for "Contact".
- **Welcome section**: Adjusted heading structure for better readability.
- **Navigation fix**: Replaced "Openings" link with "Contact".
- **CSS cleanup**: Removed redundant comment in `Hero.css` and fixed typos in alt text.
