Refactor payment methods management to utilize a paginated list view

- Updated the payment methods management handler to directly build and display a paginated list of user payment methods, enhancing user experience.
- Removed legacy support for single card checks and deprecated keyboard functions in favor of the new list view.
- Improved localization handling for payment method titles and added fallback options for missing data.
