chore(deps): update dependency @microsoft/api-extractor to v7.59.4

Why this was not classified as a code_change:

1. The error does not point at changed code.

• The failure is a Playwright assertion at webauthn-device.test.ts:100.
• getByRole('button', { name: 'Logout' }) was not visible within the 5000ms timeout after the authenticate step.
• The message mentions no function, import or module touched by the PR.

2. The PR is unrelated to the failing area.

• The only change is bumping the @microsoft/api-extractor dev dependency from 7.58.2 to 7.59.4.
• This tool generates API reports and rolls up type declarations at build time.
• It does not affect journey-app runtime or WebAuthn behaviour.
• The PR diff lists no changed source files.
• touched_projects contains * only because of the lockfile and dependency change.

3. The failure looks timing-related.

• The other test in the same file passed.
• The failing step is a browser UI flow that depends on a virtual authenticator and a render or redirect finishing within 5 seconds.
• That kind of step can pass or fail on timing alone.

4. The task has a small flake rate.

• Its flakiness rate is about 1.4%, which is above 0%.
• That is consistent with an occasional non-deterministic failure.
• Removing the dependency bump would not logically fix the failure.

5. Other checks.

• The task output was present, so the missing-output bail-out did not apply.
• No similar-failure branch was provided.
• No external-service outage is evident, so this is not environment_state.

Conclusion: this is a flaky_task. A rerun is the appropriate action, and no code changes are proposed.
