Fix: harden QA monitoring smoke docs

[ohld]

Refs FFM-1708.

What changed

• Correct QA/runbook Sentry scan commands to match the installed sentry issues list CLI syntax.
• Keep the existing e2e smoke URL-button guard covered with focused regression tests, including URL-only markup and mixed URL/callback keyboards.

Verification

• ruff check --fix src/ tests/
• ruff format src/ tests/
• git diff --check
• python3 -m pytest tests/scripts/test_e2e_smoke.py

Remaining operational action

• sentry issues list --query "is:unresolved" --max-rows 3 still reaches Sentry but returns 401 Invalid token in the CTO runtime too. The Paperclip secret metadata endpoint returns 403 Board access required for this run, so SENTRY_AUTH_TOKEN must be rotated by an owner with Paperclip/Sentry secret access before QA scans are fully restored.
