fix(#1586): Redesign logging concept for clearer test workflow output

[christophd]

Summary

• Restructure log levels across the framework so INFO reflects the test workflow with action outcome indicators (✔/✘/⊘), DEBUG provides diagnostics (message content, connection details), and TRACE absorbs SPI registration noise
• Add ANSI color support (LogColors) and configurable settings (CitrusLogSettings) for controlling colored output and message content logging
• Introduce MessagePrinter abstraction with box-drawing formatted output (DefaultMessagePrinter) for structured message display
• Refactor LoggingReporter to use the new log level hierarchy and color-coded test lifecycle output
• Consolidate HTTP interceptor logging into shared LoggingInterceptorUtils
• Update all log4j2.properties test configurations to use the new citrus logger category

Test plan

• Verify existing unit tests pass (./mvnw test -pl core/citrus-base)
• Verify LoggingReporterTest covers the redesigned reporter output
• Run integration tests to confirm log output at INFO level shows clean test workflow
• Verify ANSI colors render correctly in terminal and can be disabled via CitrusLogSettings
• Confirm DEBUG level shows message content and connection diagnostics
• Confirm TRACE level shows SPI registration details

Closes #1586
