Apply review feedback: use class reference and add unit tests

[Copilot]

Applies review feedback from PR #202 to improve maintainability and test coverage of the Sentry logging filter configuration.

Changes:

• Replace hard-coded logger string with DefaultHandlerExceptionResolver.class.getName() to prevent typos and stay in sync with refactoring
• Extract filtering logic into static filterEvent() method for testability
• Add unit tests covering filtered events (excluded logger), pass-through events (other loggers), and null logger handling

@Configuration
public class SentryLoggingFilterConfiguration {
    private static final String EXCLUDED_LOGGER =
            DefaultHandlerExceptionResolver.class.getName();

    static SentryEvent filterEvent(SentryEvent event) {
        if (EXCLUDED_LOGGER.equals(event.getLogger())) {
            return null;  // Drop excluded events
        }
        return event;
    }

    @Bean
    public SentryOptions.BeforeSendCallback sentryBeforeSendCallback() {
        return (event, hint) -> filterEvent(event);
    }
}

Pull request overview

Improves the Sentry “before send” filtering configuration by making the excluded logger reference refactor-safe and by extracting the filter logic into a testable method, with unit tests added to validate the behavior.

Changes:

• Replaced a hard-coded excluded logger string with DefaultHandlerExceptionResolver.class.getName().
• Extracted filtering logic into a static filterEvent(SentryEvent) helper for reuse/testability.
• Added JUnit tests covering excluded logger, non-excluded logger, and null logger cases.

File	Description
src/main/java/uk/ac/ox/ctl/SentryLoggingFilterConfiguration.java	Uses a class-based logger name and routes callback logic through a testable filterEvent() method.
src/test/java/uk/ac/ox/ctl/SentryLoggingFilterConfigurationTest.java	Adds unit coverage for filtered vs pass-through behavior (including null logger).

These tests only assert the result is non-null, but the method name implies the original event is passed through unchanged. Consider asserting the returned value is the same instance to better protect the intended behavior.

This test asserts non-null, but if the intended behavior is to pass the same event through when logger is null, assert the returned value is the same instance for a stronger regression check.
