build(test): reduce test output noise with context-aware verbosity

Make test logging conditional on invocation context: `gradle build`
produces quiet output (pass/fail only), while `gradle test` shows
verbose output with stdout/stderr and full stack traces for debugging.

- Add JVM args to suppress Mockito self-attach and CDS warnings
- Create logback-test.xml to eliminate /opt/app/logs file appender errors
- Reduce test log levels from DEBUG to INFO/WARN in application-test.properties
- Remove redundant System.setProperty for security DEBUG logging
- Apply same conditional logging to registerJdkTestTask

Reduces `gradle build` output from ~7,400 lines to ~1,100 lines.
