Picture Capture v2.12.9

Major changes:
- Review-window “字体” renamed to “词条字体”.
- Added independent “简体字体” controls for the editable Simplified companion: family, size, bold and italic.
- Existing projects inherit the established headword font once, then keep Simplified typography independently.
- Review “上下安全空间” renamed to “上下边距”; stored parameter semantics are unchanged.
- OCR review results are condensed to one row: P / T / L / 融 (PaddleOCR / Tesseract / Lens / fused); available values remain clickable and similarity-coloured.

Validation:
- pytest: 274 passed
- legacy run_tests.py: 70 passed
