Fix check raw file injection smoke test (#10920)

Fix flaky check raw file injection test in LogInjectionSmokeTest

Three bugs contributed to flakiness in CI on JDK 8 variants (zulu8,
semeru8) and under load:

1. Copy-paste bug in assertRawLogLinesWithInjection: the fallback
   assertion for 32-bit trace IDs incorrectly referenced logLines[0]
   (BEFORE FIRST SPAN) instead of logLines[4] (INSIDE THIRD SPAN) and
   logLines[6] (AFTER FORTH SPAN). This meant the 32-bit trace ID
   format was never actually validated for those two log lines.

2. BaseApplication.waitForCondition timeout was 10 seconds. On loaded
   CI machines with JDK 8 JVMs, the RC config change propagation through
   captureTraceConfig() could take several seconds, approaching the
   limit and causing "Logs injection config was never updated" failures.
   Increased to 30 seconds to give adequate headroom.
