- Replace in-memory Maps in aiHandoffStore with DB-backed async functions
using new patient_conversation table (stage + aiHandoff per patient)
- Add afterHoursEnabled to ai_settings table (persists across restarts)
- Fix runtime crash in reschedule-graph: mon/tue/wed variables were out
of scope in the next-week fallback branch (ReferenceError)
- Wire rescheduleGreeting and generalFallback chat templates through to
LangGraph nodes so user-configured messages take effect
- Add otherNode to reminder-graph to handle unclassified patient replies
(e.g. "I want another appointment") and route to booking flow
- Fetch chatTemplates once per webhook request instead of per stage
