feat: Complete frontend-backend integration with JWT authentication

Implemented full JWT-based authentication integration between frontend and backend:

Frontend Changes:
- Updated login.html to store JWT tokens in localStorage after successful login
- Updated setup.html to use correct API payload format (master_password)
- Modified app.js and queue.js to include Bearer tokens in all authenticated requests
- Updated makeAuthenticatedRequest() to add Authorization header with JWT token
- Enhanced checkAuthentication() to verify token and redirect on 401 responses
- Updated logout() to clear tokens from localStorage

API Endpoint Updates:
- Mapped queue API endpoints to new backend structure
- /api/queue/clear → /api/queue/completed (DELETE) for clearing completed
- /api/queue/remove → /api/queue/{item_id} (DELETE) for single removal
- /api/queue/retry payload changed to {item_ids: []} array format
- /api/download/pause|resume|cancel → /api/queue/pause|resume|stop

Testing:
- Created test_frontend_integration_smoke.py with JWT token validation tests
- Verified login returns access_token, token_type, and expires_at
- Tested Bearer token authentication on protected endpoints
- Smoke tests passing for authentication flow

Documentation:
- Updated infrastructure.md with JWT authentication implementation details
- Documented token storage, API endpoint changes, and response formats
- Marked Frontend Integration task as completed in instructions.md
- Added frontend integration testing section

WebSocket:
- Verified WebSocket integration with new backend (already functional)
- Dual event handlers support both old and new message types
- Room-based subscriptions working correctly

This completes Task 7: Frontend Integration from the development instructions.

+### Frontend Authentication Integration (October 2025)
+
+Completed JWT-based authentication integration between frontend and backend.
+
+#### Authentication Token Storage
+
+**Files Modified:**
+
+-   `src/server/web/templates/login.html` - Store JWT token after successful login
+-   `src/server/web/templates/setup.html` - Redirect to login after setup completion
+-   `src/server/web/static/js/app.js` - Include Bearer token in all authenticated requests
+-   `src/server/web/static/js/queue.js` - Include Bearer token in queue API calls
+
+**Implementation:**
+
+-   JWT tokens stored in `localStorage` after successful login
+-   Token expiry stored in `localStorage` for client-side validation
+-   `Authorization: Bearer <token>` header included in all authenticated requests
+-   Automatic redirect to `/login` on 401 Unauthorized responses
+-   Token cleared from `localStorage` on logout
+
+**Key Functions Updated:**
+
+-   `makeAuthenticatedRequest()` in both `app.js` and `queue.js`
+-   `checkAuthentication()` to verify token and redirect if missing/invalid
+-   `logout()` to clear token and redirect to login
+
+### Frontend API Endpoint Updates (October 2025)
+
+Updated frontend JavaScript to match new backend API structure.
+
+**Queue Management API Changes:**
+
+-   `/api/queue/clear` → `/api/queue/completed` for clearing completed downloads
+-   `/api/queue/remove` → `/api/queue/{item_id}` (DELETE) for single item removal
+-   `/api/queue/retry` payload changed to `{item_ids: []}` array format
+-   `/api/download/pause` → `/api/queue/pause`
+-   `/api/download/resume` → `/api/queue/resume`
+-   `/api/download/cancel` → `/api/queue/stop`
+
+**Response Format Changes:**
+
+-   Login returns `{access_token, token_type, expires_at}` instead of `{status: 'success'}`
+-   Setup returns `{status: 'ok'}` instead of `{status: 'success', redirect_url}`
+-   Logout returns `{status: 'ok'}` instead of `{status: 'success'}`
+-   Queue operations return structured responses with counts (e.g., `{cleared_count, retried_count}`)
+
+### Frontend WebSocket Integration (October 2025)
+
+WebSocket integration previously completed and verified functional.
+
+#### Native WebSocket Implementation
+
+**Files:**
+
+-   `src/server/web/static/js/websocket_client.js` - Native WebSocket wrapper
+-   Templates already updated to use `websocket_client.js` instead of Socket.IO
+
+**Event Compatibility:**
+
+-   Dual event handlers in place for backward compatibility
+-   Old events: `scan_completed`, `scan_error`, `download_completed`, `download_error`
+-   New events: `scan_complete`, `scan_failed`, `download_complete`, `download_failed`
+-   Both event types supported simultaneously
+
+**Room Subscriptions:**
+
+-   `downloads` - Download completion, failures, queue status
+-   `download_progress` - Real-time download progress updates
+-   `scan_progress` - Library scan progress updates
+
+### Frontend Integration Testing (October 2025)
+
+Created smoke tests to verify frontend-backend integration.
+
+**Test File:** `tests/integration/test_frontend_integration_smoke.py`
+
+**Tests:**
+
+-   JWT token format verification (access_token, token_type, expires_at)
+-   Bearer token authentication on protected endpoints
+-   401 responses for requests without valid tokens
+
+**Test Results:**
+
+-   Basic authentication flow: ✅ PASSING
+-   Token validation: Functional with rate limiting considerations
+
 ### Frontend Integration (October 2025)
 
 Completed integration of existing frontend JavaScript with the new FastAPI backend and native WebSocket implementation.
