fix: custom pg schema is not reliable (#278)
* fix: custom pg schema is not reliable

* fix

* fix

* fix: WorkerPoller now always has tenant extension

Ensures WorkerPoller follows same pattern as MemoryEngine - always
creates a DefaultTenantExtension if none is provided, preventing
NoneType errors when calling list_tenants().

Fixes test failures in test_worker.py

* fix: DefaultTenantExtension honors explicit schema parameter

Allows WorkerPoller's schema parameter to be passed through to
DefaultTenantExtension via config dict, maintaining backward
compatibility for tests that use schema parameter without
providing a tenant extension.

Fixes test_poller_with_custom_schema test failure.

Default single-tenant extension with no authentication.

It provides single-tenant behavior using the configured schema from

- No authentication required (passes all requests)
- Uses configured schema from environment
- Perfect for single-tenant deployments without auth
Configuration:

configure a different tenant extension:
