isheng c2c73605e0 test: set pool.provider= on mocks to avoid MagicMock truthy guard trigger
The provider-mismatch guard now checks pool_provider and
current_provider != pool_provider. MagicMock.provider returns
a truthy child mock by default, which would trigger the guard
and skip the pool recovery tests. Set pool.provider='' explicitly.

"""Regression test for #26145: credential pool rotation after interrupt-resume.
When has_retried_429 is lost (user cancels between 429s), the pool should
