feat: chatbot CDT lookup — SRP quad, 4-digit auto-prefix, quad field to Selenium

- parseSrpCode: recognize "D4341 UL" / "4341 LR" etc., store quadrant in quad field
- matchOne: auto-prefix D for 4-digit inputs like "0120" → D0120
- LLM prompt: keep SRP code and quadrant together as one procedureName entry
- CdtMatch / CdtResult: add quad field, thread through matchedCodes action data
- claim-form.tsx: include quad in chatbot_claim_prefill type and spread to service line
- selenium_claimSubmitWorker.py: pass quad to fill_service_line, select quadrant
  dropdown by index (UR=1, UL=2, LL=3, LR=4) matching MassHealth form structure
