docs: fix documentation inaccuracies in README.md

- Fix query autoStart default: true → false (matches code)
- Fix PostgreSQL publicationName example: drasi_pub → drasi_publication
- Add missing metadata field to gRPC reaction table
- Add complete field table for gRPC Adaptive reaction section
- Improve Mock source dataType description with node label info
