fix: Update embedding dimensions to 3072 and add Vercel Analytics

- Updated GOOGLE_EMBEDDING_DIMENSIONS to 3072 to match gemini-embedding-001 output
- Updated database schema embedding index from 768 to 3072 dimensions
- Recreated production database index with correct dimensions
- Added @vercel/analytics package for production analytics
- Added Analytics component to root layout

This fixes the galaxy visualization issue caused by dimension mismatch between
the embedding model output (3072) and the database index (768).
