[MNG-8432] Integration test for mixin-based property and dependency
management inheritance
* Integration test for MNG-8432 using mixins
* Use maven-it-plugin-expression instead of effective POM string matching
Replace help:effective-pom + Files.readString/String.contains with the
conventional maven-it-plugin-expression approach using
verifier.loadProperties(), which is more robust against
whitespace/formatting changes.
