refactor: complete rewrite as React+FastAPI dashboard
Replace monolithic Jinja2 template with modern stack: Backend (FastAPI): - Modular router/service architecture - Async PostgreSQL (asyncpg) for news from n8n pipeline - Live Unraid server stats (2 servers via API) - Home Assistant, Vikunja tasks, weather (wttr.in) - WebSocket broadcast for real-time updates (15s) - TTL cache per endpoint, all config via ENV vars Frontend (React + Vite + TypeScript): - Glassmorphism dark theme with Tailwind CSS - Responsive grid: mobile/tablet/desktop/ultrawide - Weather cards, hourly forecast, news with category tabs - Server stats (CPU ring, RAM bar, Docker list) - Home Assistant controls, task management - Live clock, WebSocket connection indicator Infrastructure: - Multi-stage Dockerfile (node:22-alpine + python:3.11-slim) - docker-compose with full ENV configuration - Kaniko CI/CD pipeline for GitLab registry Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
