Authentication UI and User Management

User Story

As a user, I want to register and log in to VoidRunner so that I can access my tasks and account securely.

Technical Requirements

• Create registration form with email and password validation
• Build login form with proper error state handling
• Implement JWT token storage using browser localStorage
• Add logout functionality with complete token cleanup
• Create route guards for protected pages
• Build user profile management interface

Acceptance Criteria

• Registration validates email format and password complexity
• Login form displays clear error messages for invalid credentials
• JWT tokens persist across browser sessions until logout
• Protected routes redirect unauthenticated users to login page
• Logout clears all authentication state and tokens
• Form validation provides real-time feedback to users

Definition of Done

• All authentication flows tested manually end-to-end
• Component unit tests written for auth components
• Mobile-responsive design verified on multiple devices
• Error handling covers network timeouts and server errors
• ARIA labels and keyboard navigation implemented
