Soften CLI model capability warning

[SrikarChittemsetty]

Summary

Softens the CLI model capability warning for models that have not been verified for cn.

Changes

• Rewords the warning from “not recommended” to “has not been verified”
• Keeps the warning visible while making it less definitive for unknown local/provider models
• Updates the UI test expectations to match the new wording and tolerate terminal line wrapping

Testing

Closes #12193

Summary by cubic

Softened the CLI model capability warning: unverified models for cn now say “has not been verified” and note that reasoning or tool-calling may be unreliable. Updated the UI tests to match the new text and tolerate terminal line wrapping.
