feat: Implement Phase 2 Frontend basic structure

Frontend Setup:
- Vite + React 18 + TypeScript configuration
- Material-UI v7 integration
- React Query for data fetching
- Zustand for state management
- React Router for routing

Project Configuration:
- package.json with all dependencies (React, MUI, TanStack Query, Zustand, etc.)
- tsconfig.json with path aliases (@/components, @/pages, etc.)
- vite.config.ts with dev server and proxy settings
- Dockerfile and Dockerfile.dev for production and development
- nginx.conf for production deployment
- .env and .gitignore files
- docker-compose.yml for local development

TypeScript Types:
- Complete type definitions for all API models
- User, Keyword, Pipeline, Application types
- Monitoring and system status types
- API response and pagination types

API Client Implementation:
- axios client with interceptors
- Token refresh logic
- Error handling
- Auto token injection
- Complete API service functions:
  * users.ts (11 endpoints)
  * keywords.ts (8 endpoints)
  * pipelines.ts (11 endpoints)
  * applications.ts (7 endpoints)
  * monitoring.ts (8 endpoints)

State Management:
- authStore with Zustand
- Login/logout functionality
- Token persistence
- Current user management

Pages Implemented:
- Login page with MUI components
- Dashboard page with basic layout
- App.tsx with protected routes

Docker Configuration:
- docker-compose.yml for backend + frontend
- Dockerfile for production build
- Dockerfile.dev for development hot reload

Files Created: 23 files
- Frontend structure: src/{api,pages,stores,types}
- Configuration files: 8 files
- Docker files: 3 files

Next Steps:
- Test frontend in Docker environment
- Implement sidebar navigation
- Create full management pages (Keywords, Pipelines, Users, etc.)
- Connect to backend API and test authentication
