SamoilenkoVadym	ddaa963bc2	Fix crypto error by disabling MSAL when Azure AD is not configured ... Problem: - MSAL library was causing crypto errors in browser - Black screen on load due to MSAL initialization failure - Error: crypto module not available in browser environment Solution: - Made MSAL initialization conditional based on Azure AD configuration - Only initialize MSAL if REACT_APP_AZURE_CLIENT_ID is properly configured - Allow simple login to work without MSAL for testing purposes - Gracefully handle both MSAL and simple login modes Changes: - frontend/src/context/AuthContext.tsx: * Check if Azure AD is configured before initializing MSAL * Set msalInstance to null when Azure is not configured * Updated all MSAL calls to check for null before use * Simple login works independently of MSAL - frontend/package.json: * Added crypto polyfills as devDependencies (for future use) * Packages: crypto-browserify, buffer, stream-browserify, etc. - frontend/src/styles/theme.css: * Added login form styles (login-container, login-card, form-group, etc.) Benefits: - No more crypto errors in browser - Simple login works without Azure AD configuration - Easy testing with test accounts (admin/user) - Production Azure AD login still supported when configured - Graceful fallback for environments without Azure setup Testing: - Frontend compiles successfully without crypto errors - All services running: backend, frontend, postgres, redis - Simple login working with test accounts - No black screen on load Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>	2026-01-28 10:56:54 +00:00
