Pull request overview

Updates CSFLE Queryable Encryption (QE) test coverage to avoid running deprecated prefixPreview / suffixPreview scenarios against MongoDB server versions where they’re no longer supported (9.0.0+), keeping CI green while the server/spec behavior diverges.

Changes:

• Add maxServerVersion: 8.99.99 run-on requirements to QE unified spec tests that rely on prefixPreview / suffixPreview.
• Fix mislabeled substringPreview test description in unified spec files.
• Gate/skip integration test logic and spec-suite execution paths that would fail on MongoDB 9.0.0+.

@PavelSafronov let's discuss the testing approach here as none of the affected tests seem running currently on CI.

Thanks @PavelSafronov!

I left suggestion to remove changes in change streams (we can either merge them in a separate or, if you prefer, as part of this PR but as updated spec tests, please see #4935 for more details).
Also couple of leftovers and clarifications are needed.
