feat: AI chat file uploads, RCT/PA tooth mapping, check+claim flow, service date column

- Chatbot: add paperclip button to attach X-ray/PDF files to claim submissions;
  files flow through chatbotFileStore into claim-form uploadedFiles for Selenium
- CDT lookup: auto-select D3310/D3320/D3330 by tooth number for RCT; strip #NN
  from procedure names before alias lookup so "1 pa, #3" → D0220 tooth 3;
  add "1 pa" alias for D0220; expand multi-PA notation via AI prompt rule
- AI classifier: add navigate_eligibility intent ("check mh" → /insurance-status);
  fix duplicate intent entry; add RCT and multi-PA prompt rules
- Check+claim flow: pass serviceDate through check_and_claim_ready actionData;
  tryClaimFromChatbot skips PDF preview and navigates straight to claims with
  memberId fallback lookup; wired into all provider onPdfReady callbacks
- Claims table: add Service Date column between Patient Name and Submission Date
