The full-suite gate caught a real regression: AddOtOpcUaDriverFactories' registration
now resolves ISecretResolver (for Galaxy/OpcUaClient secret: refs, Tasks 7-8), so the
two ResilienceInvokerFactoryRegistrationTests that build a minimal container and resolve
the invoker factory threw 'No service for ISecretResolver'. The real host always
registers it via AddZbSecrets (unconditional, Task 3), and GetRequiredService correctly
fails-fast for a genuinely misconfigured host — so the fix is to complete the test
container with a stub resolver, matching production composition. Test-only.
