Documents forward_headers for agent integrations.

Changes

• New page product/agent-gateway/forwarding-headers.mdx, modeled on the MCP forwarding headers page: config forms, renames, headers that are never forwarded, header priority, an A2A example
• Added to the Agent Gateway nav and linked from the Agent Registry page

Testing

• Behaviour described matches the gateway change (Portkey-AI/gateway-enterprise-node, feat/agent-forward-headers); not previewed locally
