Depends on #1689
Based on #1689

Description of the change:

Various fixes trying to get itest suite into better state.

1. Set quarkus.http.test-port=0 so that Quarkus chooses a random available port for the Cryostat HTTP port, rather than hardcoding to 8081. This didn't end up helping as intended, but it seems worth keeping.
2. Shut down the WORKER executor threadpool in WebSocketTestBase to ensure async tasks from a test run don't continue running during the next test run.
3. Add a timeout 1h to PR CI runs so hanging runs should terminate sooner.
4. Split out AgentHeapDumpGraphQLIT from AgentHeapDumpIT, like test(async-profiler): split GraphQL integration tests into separate file #1689
5. Add missing audit tracking entities for thread dumps and heap dumps to GraphQL mutation implementations
6. Add test assertions for GraphQL responses - if a GraphQL query or mutation fails, the HTTP response status code is still 200, but the JSON GraphQL body will indicate an error. These were not previously checked in depth, so GraphQL failures would not be caught immediately and could lead to strange-looking cascaded failures later in tests.

I find that this works better and gets the test suite passing on my development workstation, but there are still issues on my laptop and in CI.
