UI: login and access

[kartpop]

Is your feature request related to a problem? Please describe.

Currently, there is no user authentication or access management interface for the console. Users cannot securely log in, manage their accounts, or control access to resources. This creates security risks and prevents proper user management. Without a login system, we cannot track usage, enforce quotas, or provide personalized experiences.

Describe the solution you'd like

Build a comprehensive authentication and access management UI with the following capabilities:

1. Login Interface

   • Clean, modern login page
   • Email/password authentication
   • "Remember me" functionality
   • Password strength indicator
   • "Forgot password" flow with email verification

2. User Registration

   • Self-service signup flow
   • Email verification required
   • Terms of service and privacy policy acceptance
   • Organization/project setup during onboarding

3. Access Management Dashboard

   • User profile management (name, email, avatar, preferences)
   • Password change functionality
   • API key generation and management
   • Session management (view active sessions, logout from other devices)
   • Two-factor authentication (2FA) setup
