feat: Add File Test tab to Game Reader Test plugin
Added new 'File Test' tab that allows testing OCR on saved screenshot files. This is useful when: - The game is not currently running - You want to test OCR on a specific saved screenshot - You want to compare OCR results on the same image Features: - Browse button to select image files (PNG, JPG, BMP, TIFF) - Backend selection (Auto/EasyOCR/Tesseract) - Displays filename and processing stats - Shows which backend was used and processing time The original 'Quick Test' still captures the current screen. The new 'File Test' lets you test on saved images.
