ci: add Gitea Actions CI/CD with Portainer deployment

Add complete CI/CD pipeline:
- Gitea Actions workflow (build + deploy)
- Multi-stage Dockerfile (Node build + nginx serve)
- nginx config with SPA routing and cache headers
- docker-compose.yml for local testing
- .dockerignore to optimize build

Pipeline flow:
1. Build job: npm ci + npm build + upload artifact
2. Deploy job (main only): Docker build + push to registry + Portainer webhook

Requires Gitea secrets:
- DOCKER_USERNAME
- DOCKER_PASSWORD
- PORTAINER_WEBHOOK_URL
