fix: suppress SpotBugs warnings in AuthenticationService and PlatformLogin (#184)

- Added @SuppressFBWarnings("EI_EXPOSE_REP2") to setRestTemplate methods
  to avoid exposing internal mutable RestTemplate objects.
- Removed redundant null check in SecretServerFactoryBean
- Keeps SpotBugs check passing without changing functionality.
- updated document
