fix: stop bandwidth measurements on terminal HTTP errors

[devandrepascoa]

Stops a SpeedTest after terminal bandwidth or loaded-latency failures, records the failure on the affected phase result, and forwards its HTTP status to onError. Only 429 responses retry (up to three times, honoring Retry-After); pending retry callbacks are cancelled when a test is paused or restarted.

[ask-bonk]

PR adds token replacement and treats HTTP authorization failures as terminal for bandwidth requests.

Submitted 2 inline correctness findings.

Validation passed: focused unit test, TypeScript check, oxlint, and format check.

Summary
Propagates bandwidth HTTP status codes through onError, stops the engine on non-OK responses, and adds HTTP-error E2E coverage.

Submitted 3 inline correctness findings.

Validation: git diff --check passed. Unit tests could not run because pnpm is unavailable in this environment.
