	Shared quiet-by-default Logback config for the whole reactor's tests.

	Referenced by every module's Surefire execution via the root pom's
	maven-surefire-plugin <systemPropertyVariables>:

		<logback.configurationFile>${maven.multiModuleProjectDirectory}/src/test/resources/logback-test.xml</logback.configurationFile>

	Using the logback.configurationFile system property (rather than a per-module
	classpath logback-test.xml) gives one authoritative source with no drift.

	Policy: root level=WARN so genuine warnings/errors STILL print - only INFO
	startup chatter is removed.  Named loggers below are silenced only because
	expected negative-path tests intentionally trigger those libraries; the list
	is a harmless superset (a logger that never fires in a given module is a no-op).
	Never set the root to OFF.
