gemini-3-flash-preview was hallucinating year (e.g., returning 1993
instead of 2023 for position-10 code P). Prompt now includes the full
1980-2039 year code table and position-7 disambiguation rule.

The 5s cloud timeout was too tight for the initial WIF authentication
which requires 3 HTTP round-trips (STS, IAM credentials, resource
manager). First call took 5.5s and was discarded, falling back to slow
CPU-based PaddleOCR. Increased to 10s to accommodate cold-start auth.

CloudEngine wraps Google Vision TEXT_DETECTION with lazy init.
HybridEngine runs primary engine, falls back to cloud when confidence
is below threshold. Disabled by default (OCR_FALLBACK_ENGINE=none).

Introduce pluggable OcrEngine ABC with PaddleOCR PP-OCRv4 as primary
engine and Tesseract wrapper for backward compatibility. Engine factory
reads OCR_PRIMARY_ENGINE config to instantiate the correct engine.
