E2EUITests

GrpahQL - a component was not found

Start by running the failing tests named in the report: XForwardHeadersProxyTest.java:117, AuthenticationHaTest.java:61, and the E2EUITests GraphQL case. Trace the intermittent header, authentication, and component-not-found failures in their respective test setups. Done means the identified flaky tests pass reliably without masking the reported assertions.
