refactor: Implement dependency injection for handlers and services

- Refactored AuthHandler, UserHandler, TextureHandler, ProfileHandler, CaptchaHandler, and YggdrasilHandler to use dependency injection.
- Removed direct instantiation of services and repositories within handlers, replacing them with constructor injection.
- Updated the container to initialize service instances and provide them to handlers.
- Enhanced code structure for better testability and adherence to Go best practices.
