fix: use load() helper in order tests for proper Effect service resolution

The new order tests called Agent.list() and Agent.get() directly,
which return Effect objects rather than resolved values. All existing
tests use the load() helper which properly provides the Effect service
layer via Effect.runPromise.

This fixes the unit test failures on both linux and windows CI.
