Outbound HTTP clients (NDC call routing)

Each NDC upstream call uses a different HTTP library so workspace E2E exercises all agent HttpClient instrumentations.

OTA API	NDC path	HTTP client
POST /api/flights/search	/airshopping	Spring RestTemplate
POST /api/flights/book	/offerprice	Apache HttpClient 4 (sync)
	/ordercreate	OkHttp 3
POST /api/flights/payandissue	/orderchange	OpenFeign
POST /api/flights/orders/query	/orderretrieve	Spring WebClient
POST /api/flights/refund/process	/ordercancel	Ning async-http-client
POST /api/flights/change	/airshopping (optional)	JDK HttpURLConnection
	/orderchange	Apache HttpClient 3
POST /api/flights/baggage/purchase	/servicelist	OkHttp 3
	/orderchange	Apache HttpClient 4 (async)

Routing is implemented in org.example.ndc.http.NdcHttpRouter.
