Update Logback smoke tests to use new assertion framework and extend framework for MessageData and ExceptionData

[Copilot]

This PR updates the Logback smoke tests to use the new assertion framework introduced in #4141 and extends the framework to support MessageData and ExceptionData assertions.

Changes Made

Framework Extensions

1. Added MessageAssert class - Provides fluent assertions for MessageData with methods like:

   • hasMessage() - Assert message content
   • hasSeverityLevel() - Assert severity level
   • hasProperty() - Assert properties
   • hasPropertiesSize() - Assert property count

2. Added ExceptionAssert class - Provides fluent assertions for ExceptionData with methods like:

   • hasExceptionType() - Assert exception type
   • hasExceptionMessage() - Assert exception message
   • hasSeverityLevel() - Assert severity level
   • hasEmptyProperties() - Assert no properties (for non-logger exceptions)

3. Extended TraceAssert - Added support for:

   • hasMessageSatisying() - Assert message data in trace
   • hasExceptionCount() - Assert exception count
   • hasExceptionSatisying() - Assert exception data in trace

Test Updates

LogbackTest.java

• Converted test() method to use new framework for asserting message data
• Converted testWithException() method to use new framework for asserting exception data
• Maintained conditional logic for Wildfly vs non-Wildfly server differences

LogbackDisabledTest.java & LogbackLevelOffTest.java

• Updated both test methods to use new assertion framework
• Simplified exception handling using new ExceptionAssert class

Benefits

• Cleaner test code: Removes manual casting and envelope extraction
• Better readability: Fluent API makes test intentions clearer
• Consistent with framework: Aligns with the assertion pattern used in other tests
• Maintainable: Centralized assertion logic in reusable classes

Example Usage

Before:

List<Envelope> rdList = testing.mockedIngestion.waitForItems("RequestData", 1);
Envelope rdEnvelope = rdList.get(0);
RequestData rd = (RequestData) ((Data<?>) rdEnvelope.getData()).getBaseData();
assertThat(rd.getName()).isEqualTo("GET /Logback/test");

After:

testing.waitAndAssertTrace(trace -> 
    trace.hasRequestSatisying(request -> 
        request.hasName("GET /Logback/test").hasSuccess(true)));

The tests now use the same modern assertion framework introduced in #4141, making them more maintainable and consistent with the rest of the codebase.

LogbackDisabledTest and LogbackLevelOffTest are failing

Note: Generally you shouldn't run all of the smoke tests, as they can take a long time.
Instead, focus on running a single test.

# Run a specific smoke test
./gradlew :smoke-tests:apps:HttpClients:smokeTest --tests "*HttpClientTest\$Tomcat8Java8Test"

Fixed the failing LogbackDisabledTest and LogbackLevelOffTest. The issue was that the tests were expecting .hasSuccess(true) but the /testWithSpanException endpoint returns a 500 error code (making success=false) because it throws a RuntimeException. Updated both tests to expect .hasSuccess(false) instead. (b5c093d)
