Refactor styles and imports for consistency and maintainability:

- **CSS restructuring**: Moved `styles` folder into `src` for better organization.
- **Updated imports**: Adjusted component CSS imports to reflect new paths.
- **Component tweaks**:
  - Increased HoverCard width from `350px` to `400px` for better visual balance.
  - Adjusted Footer layout: reorganized copyright and added email link.
  - Modified Drinks circle dimensions (from `6em` to `9em`) for improved design.
- **Footer styles**: Changed copyright section's layout with top spacing and border adjustments.
