🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Add regression tests for the empty-response contract.

The supplied UpstageArticleSummaryClientTest verifies only request fields. Add cases for message == null, blank content, and finish_reason mapping. Assert that the ArticleSummaryExternalApiException message includes finish_reason only when the response provides it.

Also applies to: 228-230
