refactor(lib-checkout,lib-crm): replace SelectedCustomerFacade with CrmTabMetadataService

Remove the redundant SelectedCustomerFacade which was just a thin wrapper
around CrmTabMetadataService. Update all consumers to use CrmTabMetadataService
directly for better consistency and reduced indirection.

Changes:
- Remove SelectedCustomerFacade and its exports
- Update reward catalog components to use SelectedCustomerBonusCardsResource
- Replace local resource factories with global resources
- Update purchase options modal and customer details components
- Simplify reward action component logic and improve button state handling
