fix(tests): fix 3 failing dispatch tests

- test_registry_all_types: skip non-EnvConfig stubs (e.g. TestPluginConfig)
- test_processors_delegation: use None instead of abstract PreTrainedConfig
- test_custom_get_env_processors_override: use DataProcessorPipeline for isinstance check (PolicyProcessorPipeline is a subscripted generic)
