fix(crm-data-access, customer-details, reward-shopping-cart): persist selected addresses across navigation flows

Implement address selection persistence using CRM tab metadata to ensure
selected shipping addresses and payers are retained throughout the customer
selection flow, particularly when navigating from Kundenkarte to reward cart.

Changes include:
- Create PayerResource and CustomerPayerAddressResource to load selected
  payer from tab metadata with fallback to customer as payer
- Create PayerService to fetch payer data from CRM API with proper error
  handling and abort signal support
- Update BillingAndShippingAddressCardComponent to prefer selected addresses
  from metadata over customer defaults, with computed loading state
- Refactor continue() flow in CustomerDetailsViewMainComponent to load
  selected addresses from metadata before setting in checkout service
- Add adapter logic to convert CRM payer/shipping address types to checkout
  types with proper type casting for incompatible enum types
- Implement fallback chain: metadata selection → component state → customer
  default for both payer and shipping address

This ensures address selections made in the address selection dialogs are
properly preserved and applied when completing the customer selection flow,
fixing the issue where addresses would revert to customer defaults.
