Refactor Dropdown Handlers and Update WordPress Integration

- Updated dropdown onChange handlers across multiple components to use direct value passing instead of event target value for improved clarity and consistency.
- Changed `url` to `site_url` in WordPress integration configuration for better semantic clarity.
- Enhanced Vite configuration to include `fast-deep-equal` for compatibility with `react-dnd`.
- Updated navigation paths in `SiteContentEditor` and `SiteList` for consistency with new routing structure.
