Enhance payment processing and user detail updates in YooKassa integration

- Added handling for 'waiting_for_capture' event in the YooKassa webhook to manage bind-only payment flows, including saving payment methods and canceling authorizations.
- Introduced a new method in the YooKassaService to cancel payments, improving error handling and logging for payment cancellations.
- Updated user detail synchronization to conditionally update descriptions only when they differ from the current panel state, enhancing efficiency.
