New Update:

1. I have created a new table institutions_designations in the mup schema in the postgres database with institutions and their designation data.
2. I have created an API endpoint in the backend/app.py to get all the designations of an institution based on the institution name.
3. I have called the API endpoint in the frontend/src/pages/Search.tsx and stored the designations data.
4. I have updated the JSON-LD markup for schema.org in frontend/src/components/InstitutionMetadata.tsx with the institution designations.
