test(e2e): wait for durable terminal statuses

[igor-kupczynski]

Description

Stabilizes the TypeScript durable e2e test that checks a parent task catching a failed child run. The test now waits for the child run to reach FAILED and the parent run to reach COMPLETED instead of stopping on any non-null status such as QUEUED or RUNNING.

Refs #4204

Type of change

• Bug fix (non-breaking change which fixes an issue)
• Test changes (add, refactor, improve or change a test)

What's Changed

• Wait for the durable child run to reach FAILED before asserting.
• Wait for the durable parent run to reach COMPLETED before asserting.
• Add poll labels so timeout messages identify which run status was pending.

Checklist

Changes have been:

• Tested (unit, integration, or manually with steps specified)
• Linted and formatted

Testing

• pnpm exec prettier src/v1/examples/durable/durable.e2e.ts --check
• pnpm exec eslint src/v1/examples/durable/durable.e2e.ts
• pnpm exec tsc --noEmit
• Not run: database-backed pnpm test:e2e, per local DB safety constraints. CI should cover the TypeScript test-e2e and old-engine-new-sdk jobs.
