Fix issues #6, #7, #11, #12, #13: med reminders, push notifications, auth persistence, scheduling conflicts

- Fix TIME object vs string comparison in scheduler preventing adaptive med
  reminders from ever firing (#12, #6)
- Add frequency filtering to midnight schedule creation for every_n_days meds
- Require start_date and interval_days for every_n_days medications
- Add refresh token support (30-day) to API and bot for persistent sessions (#13)
- Add "trusted device" checkbox to frontend login for long-lived sessions (#7)
- Auto-refresh expired tokens in both bot (apiRequest) and frontend (api.ts)
- Restore bot sessions from cache on restart using refresh tokens
- Duration-aware routine scheduling conflict detection (#11)
- Add conflict check when starting routine sessions against medication times
- Add diagnostic logging to notification delivery channels
