feat: Phase 1 - Complete authentication system with JWT

Backend Implementation (FastAPI + MongoDB):
- JWT authentication with access/refresh tokens
- User registration and login endpoints
- Password hashing with bcrypt (fixed 72-byte limit)
- Protected endpoints with JWT middleware
- Token refresh mechanism
- Role-Based Access Control (RBAC) structure
- Pydantic v2 models and async MongoDB with Motor
- API endpoints: /api/auth/register, /api/auth/login, /api/auth/me, /api/auth/refresh

Frontend Implementation (React + TypeScript + Material-UI):
- Login and Register pages with validation
- AuthContext for global authentication state
- API client with Axios interceptors for token refresh
- Protected routes with automatic redirect
- User profile display in navigation
- Logout functionality

Technical Achievements:
- Resolved bcrypt 72-byte limit (replaced passlib with native bcrypt)
- Fixed Pydantic v2 compatibility (PyObjectId, ConfigDict)
- Implemented automatic token refresh on 401 errors
- Created comprehensive test suite for all auth endpoints

Docker & Kubernetes:
- Backend image: yakenator/site11-console-backend:latest
- Frontend image: yakenator/site11-console-frontend:latest
- Deployed to site11-pipeline namespace
- Nginx reverse proxy configuration

Documentation:
- CONSOLE_ARCHITECTURE.md - Complete system architecture
- PHASE1_COMPLETION.md - Detailed completion report
- PROGRESS.md - Updated with Phase 1 status

All authentication endpoints tested and verified working.
