Add unit tests for classloader-test-library module

[Copilot]

The classloader-test-library module in sample-parent/sample-features/dynamic-dependencies lacked test coverage. This module provides SPI consumer abstractions for validating classloader behavior across dependency scopes (standard, dynamic, external).

Changes

Test Coverage (13 tests)

• DependencySPIConsumerTest - validates successful SPI loading via ServiceLoader with mock implementation
• DynamicDependencySPIConsumerTest - validates error handling when SPI unavailable
• ExternalDependencySPIConsumerTest - validates external dependency SPI behavior

Test Infrastructure

• MockStringProviderSPIAsDependency - test implementation of StringProviderSPIAsDependency interface
• META-INF/services descriptor for ServiceLoader discovery

Tests verify:

• SPI loading via ServiceLoader.load() with present/absent implementations
• Optional<S> handling in AbstractSPIConsumer.getSPIImpl()
• Generic transform() functionality with various return types
• Error message generation for missing services

Example test pattern:

@Test
void testGetValue_withSPILoaded() {
    DependencySPIConsumer<String> consumer = new DependencySPIConsumer<>();
    String value = consumer.getValue();
    
    assertEquals("Mock value from dependency", value);
}

@Test
void testTransform_withIntegerReturn() {
    DependencySPIConsumer<Integer> consumer = new DependencySPIConsumer<>();
    Integer length = consumer.transform(String::length);
    
    assertTrue(length > 0);
}

Original prompt

Please create a new branch based on ypiel/QTDI-1914_sample_connector_dyndeps. Your goal is to add relevant unit test in sub-modules of sample-parent/sample-features/dynamic-dependencies. Maybe you will have to refactor a little exisintg code to be able to add unit test.
