refactor: align addressbook module to MintyPHP\Module\AddressBook namespace

Migrates addressbook service classes from core namespace
(MintyPHP\Service\AddressBook\*) to proper module namespace
(MintyPHP\Module\AddressBook\Service\*), consistent with the
bookmarks module pattern.

Moved to module:
- AddressBookService → modules/addressbook/lib/Module/AddressBook/Service/
- AddressBookServicesFactory → modules/addressbook/lib/Module/AddressBook/Service/
- AddressBookServiceTest → modules/addressbook/tests/Module/AddressBook/Service/
- Pages, templates, CSS, JS all in module directory

All module PHP classes now live under MintyPHP\Module\<Name>\*,
enforced by ModuleStructureContractTest::testModuleClassesUseModuleNamespace.
