Refactor CreateEventDialog and EventsPage components to integrate wallet selection

- Removed the wallet input field from CreateEventDialog, now auto-selecting the preferred wallet using PaymentService.
- Updated event creation logic in EventsPage to retrieve the wallet's admin key dynamically, ensuring better wallet management.
- Added error handling for wallet availability, enhancing user feedback during event creation.

These changes streamline the event creation process by automating wallet selection, improving the overall user experience.
