feat: add authz-adapter service and Envoy ext_authz integration
- Implemented authz-adapter deployment and service for Envoy gRPC authorization. - Created PowerShell script to generate JWK for JWT authentication. - Documented the integration of ext_authz with user-rpc.ValidateToken in ENVOY_EXT_AUTHZ_ADAPTER.md. - Added comprehensive Envoy Gateway configuration guide with JWT authentication and access control in ENVOY_GATEWAY_GUIDE.md.
