bug: flaky tests workflow failed

The nightly flaky tests workflow has failed. This indicates external API rate limiting, RPC reliability issues, or other intermittent failures that may affect users.

Check the [flaky tests workflow page](https://github.com/base/base-anvil/actions/runs/26427485118
) for details.

This issue was raised by the workflow at `.github/workflows/test-flaky.yml`.

Start with the flaky tests workflow at .github/workflows/test-flaky.yml and inspect the linked workflow run for the specific failing tests or external-service errors. Determine whether the failure is caused by rate limiting, RPC reliability, or another intermittent condition. Done means the underlying failure is addressed and the flaky workflow completes successfully.
