Refactor: merge SettingsController into ProfileController

Removed SettingsController and moved its logic into ProfileController, consolidating user profile, account, GDPR, network, and two-factor authentication actions. Updated routes, behaviors, and view files to reflect the new structure. Also updated composer.json to use pcrt/yii2-usuario and pcrt/yii2-select2, added 'surname' to Profile model, and added new attributes to User model. Improved user feedback by redirecting after key actions instead of rendering message views.
