Keep TrueNAS safety assertions independent of Markdown wrapping

PR #2456 run 37175962472 rejected retained safety warnings only because of a line break and sentence capitalization. Normalize prose for these assertions without removing any required warning or diagnostic field.

Contract-Neutral: Documentation test presentation normalization only; no runtime, API or safety-guidance change.
