create-pull-request draft expression is dropped from handler config

[strawgate]

When safe-outputs.create-pull-request.draft is set via expression (e.g. ${{ inputs.draft-prs }}), the value is not propagated to GH_AW_SAFE_OUTPUTS_HANDLER_CONFIG.

Result: create_pull_request handler does not receive draft, so it falls back to default draft behavior.

Expected: expression-based draft values should be preserved and honored at runtime (same as other dynamic config fields).

unfortunately this really technically applies to any safe-output setting which doesn't actually impact compilation decisions like permissions -- including like close-older-issues, etc

Yes I will template-ify the frontmatter... carefully.
