🎉 v4.1 Update: UI Improvements & Model Version Display

Header shows OCR-2 model badge · Footer displays v4.1 · OCR-2

• 🏷️ OCR-2 Model Badge — Header now shows a prominent OCR-2 badge so users instantly know the model version
• 🎨 Table Rendering Fix — OCR-detected tables now display with white backgrounds, dark text, and zebra striping for clear readability (previously appeared as dark/unreadable blocks)
• 📡 Health API model_version — /health endpoint now returns "model_version": "DeepSeek-OCR-2" for programmatic version detection
• 🔖 Footer Version — Updated to v4.1 · OCR-2

🎉 v4.0 Update: DeepSeek-OCR-2 Model Upgrade!

🚀 Major model upgrade to DeepSeek-OCR-2 (Visual Causal Flow) — better accuracy, higher resolution!

✨ What's New in v4.0

• 🧠 DeepSeek-OCR-2 Model - Upgraded to the latest DeepSeek-OCR-2 with Visual Causal Flow architecture
• 🔬 Higher Resolution - Dynamic resolution up to (0-6)×768×768 + 1×1024×1024 (was 640×640)
• ⚡ Flash Attention 2 - Native flash_attention_2 support on CUDA for optimal inference speed
• 🎯 Improved Accuracy - Better document understanding, chart parsing, and text recognition
• 🔄 Full Backward Compatibility - All 7 recognition modes, REST API, and frontend unchanged
• 🐳 Docker v4.0 - New all-in-one image with pre-downloaded OCR-2 model (Dockerfile.v4.0)
