Replaced all alert() calls with react-hot-toast notifications for better
user experience. Toast notifications are non-blocking, auto-dismiss, and
provide visual feedback with icons based on message type.
Changes:
- EventChatPage: Match request success/error toasts
- MatchChatPage: Video file selection and WebRTC connection error toasts
- MatchesPage: Match accept/reject action toasts
- RatePartnerPage: Rating submission and validation toasts
- VerifyEmailPage: Email verification sent toast
- ScheduleConfigSection: Schedule save success/error toasts
- MatchingConfigSection: Deadline save success/error toasts
All toast notifications use appropriate types (success, error, warning, info)
for better visual distinction and user feedback.
Split large EventDetailsPage (545 lines) into smaller, focused components:
- QRCodeSection: QR code display and copy link functionality
- ParticipantsSection: participants list with avatars
- MatchingConfigSection: deadline and matching controls
- ScheduleConfigSection: division slot configuration
EventDetailsPage now 148 lines (-73%)
