refactor: Clean up imports and unused variables in ticket-related components

- Remove unused imports from PurchaseTicketDialog.vue and useUserTickets.ts for improved code clarity.
- Update events.ts to eliminate the unused paymentRequest parameter in payInvoiceWithWallet function.
- Simplify MyTickets.vue by removing the unused unregisteredTickets variable and related QR code generation logic, enhancing maintainability.
