Exclude Spring password authority factor in tests

Refer to Spring documentation at:

* https://docs.spring.io/spring-security/reference/api/java/org/springframework/security/core/authority/FactorGrantedAuthority.html
* https://docs.spring.io/spring-security/reference/servlet/authentication/mfa.html#emfa
* https://spring.io/blog/2025/10/21/multi-factor-authentication-in-spring-security-7#how-spring-security-models-mfa-through-progressive-authorization

THis is a simple attempt to allow the creation of an incremental build
that can be used for more testing with plugin BOM and the acceptance
test harness.
