Macky 94e75238a3 fix(chat): resume unfinished session without re-picking scenario; detect win/loss from real-LLM text ...

- start_session now RESUMES an existing ACTIVE session for the persona instead of creating
  a new one / forcing re-pick of the scenario (keep original scenario+messages).
- send_message falls back to a text-based decision detector (_detect_customer_decision)
  because real LLMs rarely emit structured meta.decision — so a customer who says
  'ซื้อไม่ไหว'/'no thanks' now actually ENDS the chat as lost (was stuck active forever).
  Fragments handled in TH + EN; buy + walk.
All 11 backend suites pass. Rebuilt dist.
