ci(integration): add timeout, broaden health check, fix paths-ignore

- timeout-minutes: 15 prevents runaway jobs from consuming CI minutes
- Wait for cloudformation, s3 and stepfunctions before deploying rather
  than cloudformation alone, reducing flaky failures on slow starts
- paths-ignore: "**/*.md" to correctly ignore markdown in subdirectories
