Adds demo login page with demo account creation

Implements a new login page that allows users to either log in with credentials or quickly create a demo account. This is done to provide a quick onboarding experience for new users without requiring them to go through a full registration process. The demo account comes pre-funded with test currency, making it easy to explore the platform's features. A toggle is included to switch between demo account creation and standard login.
