test: Ensure test is server running

[philipphofmann]

Ensure that the test server is running with a retry mechanism to avoid flakiness in CI.

#skip-changelog

Note

Adds a retry-based test server readiness check and stabilizes network integration tests with task cancellation, expectation tweaks, longer timeouts, and stricter assertions.

• Tests (SentryNetworkTrackerIntegrationTestServerTests.swift):
  • Server readiness: Add ensureTestServerIsRunning() to poll http://localhost:8080/ with retries before tests run.
  • Stability tweaks:
    • Add defer { dataTask.cancel() } in requests and set expect.assertForOverFulfill = false to avoid double-fulfillment.
    • Increase wait timeouts from 5 to 10 seconds.
    • For failed request test: set expect.expectedFulfillmentCount = 2 and fulfill in completion handler.
  • Stronger assertions: Use XCTUnwrap for context.response and status_code and compare extracted statusCode to 400.
