refactor: Revamp PurchaseTicketDialog and introduce useTicketPurchase composable

- Update PurchaseTicketDialog.vue to integrate authentication checks and enhance ticket purchasing flow with wallet support.
- Implement useTicketPurchase composable for managing ticket purchase logic, including payment handling and QR code generation.
- Improve user experience by displaying user information and wallet status during the ticket purchase process.
- Refactor API interactions in events.ts to streamline ticket purchasing and payment status checks.
