feat(rnotes,canvas): comments in demo mode, emoji reactions, reminders + inline picker modal

- rNotes comments now work in demo mode via in-memory thread storage
- Added emoji reactions (7-emoji palette) and date reminders on comment threads
- Reminders integrate with rSchedule API for persistent notifications
- Canvas toolbar: split Note into "Blank Note" (always available) and "From rNotes" (picker)
- Replaced browser prompt()-based pickFromList with showPickerModal (dark-themed, searchable, keyboard nav)
- Updated pickTrip, destination, and booking handlers to use the new modal
