This commit introduces a major update to the sponsor list display.
- Implements a feature to group cash sponsors below a certain amount threshold. This helps to declutter the display when there are many smaller donations.
- Adds a new `cash-group` display type to handle the rendering of these grouped sponsors.
- Completely redesigns the UI with a new color scheme, gradients, and improved typography for a more polished and visually engaging presentation.
- Updates the styling for individual sponsor cards to improve readability and visual hierarchy.
- Created sponsorList.json with details of sponsors for the event "永平新港汕河体育协会 2 周年庆联欢晚宴".
- Developed index.html to display the event title, sponsor logos, and a scrolling list of sponsors using Vue.js.
- Implemented sorting logic for sponsors based on type and amount.
- Added animations for sponsor display and ensured responsive design.
