An empty quoted entry type currently falls through as an unknown directive and is silently ignored. Reject it as a parse failure while continuing to allow empty optional fields.

Follow-up to #2534 and the maintainer-approved review discussion: #2534 (comment).

Validation: the added case fails before the fix; all 13 bootc-sysusers tests, targeted strict Clippy, formatting, and git diff --check pass. An independent code review found no actionable issues.

Assisted-by: AI. Implementation and tests were prepared with AI assistance. The contributor reviewed the patch and explicitly authorized DCO signoff and marking this PR ready for review.

I checked the failed jobs in run 38911232876. All 29 failing integration/upgrade/baseconfig/export jobs stop while building the test image: dnf download grub2-efi-x64-cc reports No package "grub2-efi-x64-cc" available from Fedora ELN. The logs also contain HTTP 500 responses from the ELN mirror. These failures occur before the sysusers change is exercised; the two required-checks failures aggregate those jobs.

I tried rerunning the failed jobs, but GitHub requires repository admin rights. Could a maintainer rerun them once the ELN package is available, or advise whether this branch should be refreshed for an upstream CI fix?

Reran failed jobs. Wait actually, @ddy314, could you rebase on main and push again. I forgot we had a CI fix for this issue
