Make document change-status idempotent for Infinity doc store (#12717)

### What problem does this PR solve?

This PR makes the document change‑status endpoint idempotent under the
Infinity doc store. If a document already has the requested status, the
handler returns success without touching the engine, preventing
unnecessary updates and avoiding missing‑table errors while keeping
responses consistent.

### Type of change

- [x] Bug Fix (non-breaking change which fixes an issue)
