test(e2e): patch args._container not the removed get_container

handle_provider_config / handle_reload_provider_config resolve the DI container
from args._container (consistent with every other interface handler); the tests
still patched a get_container symbol that no longer exists in the module. Set
_container on the mock command instead.
