Add onboarding status for facilitators separately

[amrit110]

This pull request adds a role-based filter to the onboarding status dashboard, allowing users to view either participants or facilitators. The changes include updates to both the API and frontend to support this new filtering functionality, as well as improvements to the UI and copy for clarity.

Role-based filtering and API enhancements:

• The API endpoint in route.ts now accepts a role query parameter and filters results to show only participants or facilitators accordingly. [1] [2] [3] [4]

Frontend and UI improvements:

• The main page in page.tsx adds a role filter dropdown, updates the API call to include the selected role, and refetches data when the role changes. [1] [2] [3]
• The dashboard header and description text have been updated for clarity and inclusivity.
