ConfigureSharedLogger had no production caller, so the pool's only
diagnostics (first-wins options conflicts, scheduler/close failures)
went to NullLogger. DriverFactoryBootstrap now configures it from the
driver registry factory and from the AbCip/AbLegacy probe factories
(admin-only nodes reach the pool only through Test Connect). Wiring tests
reset the pool to a null logger first, so removing the call goes red
(verified).
