feat: AI chat scheduling, claim automation, and session improvements

- Internal AI chat: schedule_appointment intent books earliest available
  slot in Column A using office hours; claim_only intent looks up latest
  past appointment for service date, asks user when two appointments are
  within 7 days, auto-triggers correct Selenium worker with mapped prices
- Gemini model updated to gemini-flash-latest; conversation history (15
  messages) passed for pronoun/reference resolution; history trimmed to
  start with user turn so Gemini doesn't reject the context
- Insurance alias file (insuranceAliases.json) replaces hardcoded siteKey
  matching; "tufs" now resolves to TUFTS_SCO
- DOB format normalized (MM/DD/YYYY → YYYY-MM-DD) before parseLocalDate;
  autoCheck now fires for all insurance types, not just MH/CMSP
- Claim form auto-submit: all handlers (MH, CCA, DDMA, UnitedDH, Tufts)
  accept formToUse and receive fee-schedule-priced form; prefillDone set
  after chatbot code prefill so autoSubmit gate opens correctly
- Chatbot: chat history persisted in sessionStorage, cleared on logout
  and auto-logout; Clear button writes fresh state synchronously; message
  history window increased to 15
- DentaQuest/TuftsSCO Selenium: "Remember me" checkbox clicked before
  sign-in to persist OTP trust cookie across sessions
