+add PaddleOCR GPU Docker image and FastAPI OCR server with entrypoint; implement OCR endpoints and consensus extraction testing

+- Add Dockerfile_paddleocr for GPU-accelerated PaddleOCR image (pre-downloads PP-OCRv4 models, exposes port 5000, healthcheck, entrypoint)
+- Add image_support_files/paddleocr-server.py: FastAPI app providing /ocr (base64), /ocr/upload (file), and /health endpoints; model warm-up on startup; structured JSON responses and error handling
+- Add image_support_files/paddleocr-entrypoint.sh to configure environment, detect GPU/CPU mode, and launch uvicorn
+- Update test/test.node.ts to replace streaming extraction with a consensus-based extraction flow (multiple passes, hashing of results, majority voting) and improve logging/prompt text
+- Add test/test.invoices.ts: integration tests for invoice extraction that call PaddleOCR, build prompts with optional OCR text, run consensus extraction, and produce a summary report
