Add test coverage for analyze_single_patent auto-download path

7 test cases covering:
- PDF on disk analyzed directly (no download)
- Auto-download from cached metadata link when PDF missing
- FileNotFoundError when no cached link available
- Cached patent without pdf_link raises FileNotFoundError
- Analysis pipeline failure returns error string gracefully
- Model override parameter forwarded to LLM
- FileNotFoundError during parsing re-raised (not swallowed)

Closes leeworks-agents/SPARC#1661
