Tooltip Collision for Contributors Across Multiple Projects

**Describe the bug**

The previous fix ensured unique tooltips when the same contributor appeared in multiple cards. However, this solution does not fully prevent tooltip collisions when the same contributor holds the same position across different projects on the same page. Issue #1059

- Display multiple projects on the same page.
- Ensure the same contributor appears in the same position in different projects.
- Observe that tooltips may still conflict.

**Are you going to work on fixing this?**

- [x] Yes
- [ ] No

**Proposed Solution**
- Extend the unique key to include the project identifier.
- This may require an index update or changes to how contributor tooltips are assigned.

**Additional Notes**
Since this requires additional effort, this issue is separate from the previous fix.
