feat: AI chat system with LangGraph, multi-step patient flows, and appointment rescheduling
- Add floating chat window Hand-off to AI toggle (per-patient) and after-hours AI toggle (global) - Add LangGraph-powered appointment reminder flow: AI introduces itself, classifies YES/NO, handles confirmation with appointment date/time - Add multi-step rescheduling flow: ASAP vs next week, tomorrow offer, Mon/Tue/Wed picker, morning/afternoon time slot — automatically updates appointment in DB - Add new patient / after-hours flow: new vs existing patient, dental insurance check, MassHealth Selenium eligibility check (auto-uses saved member ID + DOB for existing patients), self-pay fallback - Add AI Chat Settings page (Settings → Advanced) with editable greeting templates and LangGraph flow diagrams for both reminder and new-patient flows - Add Schedule a New Patient template option in chat window, starts new-patient conversation flow - Add GET/PUT endpoints for AI handoff, after-hours handoff, and AI chat templates - Add multilingual support (7 languages) across all AI reply nodes with LLM generation and hardcoded fallbacks - Add pending reschedule in-memory store and conversation stage tracking across all flows Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
