Subject: [PATCH] Features: 1) Add default `Address.objects.none()`
 placeholders in `apply_addresses` method; 2) Validate address application
 only when billing or shipping address exists;

Fixes: 1) Correct logic for optional address validation to avoid runtime errors;

Extra: 1) Change documentation settings format from "Google" to "Plain".
