This commit adds complete authentication support to the Next.js frontend, matching the existing vanilla JS implementation with session-based auth. Frontend Changes (Next.js): - Add AuthContext for global auth state management - Create login page with gradient UI matching vanilla JS design - Implement ProtectedRoute wrapper for route protection - Add logout button to Header component - Move all app pages to (protected)/ route group - Update API client with improved 401 handling - Add auth-related TypeScript types Backend Changes: - Update static file serving to support both Next.js and vanilla JS - Add support for /login route (Next.js) in addition to /login.html - Allow /_next/* routes for Next.js static assets - Redirect unauthenticated users to /login instead of /login.html Authentication Flow: 1. User visits app → AuthContext checks session by calling /api/containers 2. If 401 → Redirect to /login page 3. User submits credentials → POST /api/login 4. Backend creates session cookie → Frontend updates context 5. User can access protected routes with valid session 6. Logout destroys session and redirects to login Key Features: - Session-based auth with 7-day HTTP-only cookies - Backward compatible with vanilla JS frontend - AUTH_ENABLED=false support (skip login entirely) - XSS protection via HTTP-only cookies - CSRF protection via SameSite=Lax - No passwords stored client-side Files Added: - web-next/src/contexts/AuthContext.tsx - web-next/src/app/login/page.tsx - web-next/src/components/auth/ProtectedRoute.tsx - web-next/src/app/(protected)/layout.tsx Files Modified: - internal/api/handlers.go (static file routing) - web-next/src/app/layout.tsx (AuthProvider wrapper) - web-next/src/components/layout/Header.tsx (logout button) - web-next/src/lib/api.ts (401 handling) - web-next/src/types/index.ts (auth types) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
