fix(ui): rebuild Tailwind CSS with tooltip classes and update cache to v1.0.4

- Rebuilt Tailwind CSS to include group-hover:opacity-100 utility class
- Fixed tooltip visibility issue (tooltips were showing permanently)
- Root cause: Tailwind CSS was stale and missing required utility classes
- Updated cache-busting version from v1.0.3 to v1.0.4
- Tooltips now correctly hidden by default, visible only on hover
