Feature Request: Implement User Authentication System

Description

Currently, ClaimVision AI is accessible without authentication. Implement a secure user authentication system so that users can create accounts, log in, and manage their own claim history.

Objectives

• Secure access to the application
• Protect user-specific claim data
• Enable future features such as claim history and personalized dashboards

Requirements

• User Registration
• User Login
• Secure Password Hashing (bcrypt)
• Session Management
• Logout Functionality
• Protected Dashboard
• Remember Logged-in Users
• Input Validation
• Friendly Error Messages

Acceptance Criteria

• Users can create a new account.
• Users can log in using valid credentials.
• Passwords are securely hashed before storage.
• Sessions persist until logout.
• Unauthorized users cannot access protected pages.
• Users can securely log out.
• Proper validation for invalid inputs.
• Existing application functionality remains unaffected.

Implemented in PR #5 using streamlit-authenticator (by mkhorasani) — login, registration with YAML persistence, bcrypt password hashing, and encrypted JWT session cookies. Default account: admin / admin123.
