feat(p7-04): fill auth & config-check stubs — 1 written, 39 deferred

auth_test.go (6): T:153 GetAuthErrClosedState written as pure unit test;
T:147/149-152 use RunServer/RunServerWithConfig → deferred.
auth_callout_test.go (31): all use NewAuthTest (RunServer) → all deferred.
config_check_test.go (3): depend on Go .conf-format parser not yet ported → deferred.
Adds 7 new test methods to AuthHandlerTests; suite grows 638→645.
