fix: correct syntax errors in test_llm_triage.py

- Wrap multi-line `with` statement in parentheses (was missing
  backslash continuations, causing SyntaxError on collection)
- Fix broken string literal on lines 67-68 by using \n escape
  instead of a raw newline inside a single-quoted string

Fixes #1329
