fix: specify google-java-format 1.7 for Java 11 compatibility

- Update build.gradle to use google-java-format version 1.7
- This resolves the Spotless Java formatting IllegalAccessError with Java 11
- Version 1.7 works with Java 11 without requiring JVM module arguments
- Includes Spotless auto-formatting fixes for Util.java and DefaultJwtServiceTest.java
