Multi-session master classes are a series — once the first session
passes, the group has started and registration closes. Changed all
MC date logic from "latest slot" / "any future slot" to "earliest slot":
- DashboardSummary: upcoming = earliest slot >= today
- McRegistrationsTab: archive = earliest slot < today
- AddBookingModal: only show MCs where earliest slot >= today
- Public MasterClasses: isUpcoming checks earliest slot
- #1 Delete confirmation dialog before removing bookings
- #2 Error toasts instead of silent .catch(() => {})
- #3 Optimistic rollback — UI reverts on API failure
- #4 Loading indicator on reminder status buttons
- #5 Search results are now actionable (status change + delete)
- #6 New bookings banner instead of full tab remount
- #7 Error states for failed data loads
- #8 InlineNotes only saves on blur when value changed
- #9 AddBookingModal supports Instagram/Telegram fields
- #10 Polling pauses when browser tab is hidden
- #11 Enter key submits ConfirmModal
Phase 1 — Refactor:
- Split monolith _shared.tsx into types.ts, BookingComponents, InlineNotes,
GenericBookingsList, AddBookingModal, SearchBar (no more _ prefix)
- All 3 tabs use GenericBookingsList — shared status workflow, filters, archive
Phase 2 — Features:
- DB migration 13: add notes column to all booking tables
- Inline notes with amber highlight, auto-save 800ms debounce
- Confirm modal comment saves to notes field
- Manual add: 2 tabs (Занятие / Мероприятие), filters expired MCs, Open Day support
- Search bar: cross-table search by name/phone
- 10s polling for real-time updates (bookings page + sidebar badge)
- Status change marks booking as seen (fixes unread count on reset)
- Confirm modal stores human-readable group label instead of raw groupId
- Confirmed group bookings appear in Reminders tab
