docs(influxdb3): use shared Grafana docs for all v3 products, fix product and token naming

- Update Core and Enterprise to use shared v3-process-data/visualize/grafana.md
- Fix product name references to use proper {{% product-name %}} shortcode
- Correct token terminology (admin token, database token) across products
- Add HTTP/2 requirement note for SQL queries through Grafana (uses Flight SQL/gRPC)
- Update Flight client library reference to clarify gRPC and Arrow Flight
- Reorganize Grafana screenshot files to use /influxdb/ directory
- Add Cloud Serverless InfluxQL screenshot
