### What problem does this PR solve?
Codecov’s coverage report shows that several RAGFlow code paths are
currently untested or under-tested. This makes it easier for regressions
to slip in during refactors and feature work.
This PR adds targeted automated tests to cover the files and branches
highlighted by Codecov, improving confidence in core behavior while
keeping runtime functionality unchanged.
### Type of change
- [x] Other (please describe): Test coverage improvement (adds/extends
unit and integration tests to address Codecov-reported gaps)
### 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] Refactoring test case
### What problem does this PR solve?
- Rename `api_key` fixture to `HttpApiAuth` across all test files

The rename better reflects the fixture's purpose as an HTTP API
authentication helper rather than just an API key.
