Adds proper initialization for checkbox fields on page load:
- address_confirm_with_recipient (Уточнить адрес у получателя)
- customer_is_recipient (Покупатель является получателем)
These fields are already tracked by autosave.js and properly saved
by backend, but were not displaying saved values after page reload.
