feat: booking UX improvements — waiting list, card focus, sort order

- Auto-note "Лист ожидания" for registrations when class is full
- Waiting list triggers on confirmed count (not total registrations)
- Card highlight + scroll after status change
- Hover effect on booking cards
- Freshly changed cards appear first in their status group
- Polling no longer remounts tabs (fixes page jump on approve)
- Fix MasterClassesData missing waitingListText type
- Add Turbopack troubleshooting docs to CLAUDE.md
