fix(tests): make flaky mocks URL-aware to prevent cross-test contamination

Position-dependent fetch mocks in hetzner-cov and digitalocean-token tests
broke when running in the full suite due to leaked async operations from
other test files shifting the call count. Switch to URL-based routing so
responses are correct regardless of call order.
