All PHP namespaces and related references have been updated from Da\User to pcrt\User throughout the codebase, including composer.json autoload settings and all source files. This change standardizes the project under the new pcrt\User namespace for improved clarity and maintainability.
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.
