- Add ProductionIdInput widget with placeholder and multi-line support
- Add UIConfig class for font family, font size, and input width settings
- Refactor data extraction tab to use horizontal PanedWindow layout
  - Left panel: Production ID text input (draggable width)
  - Right panel: control panel and log output
- Share Production IDs between data extraction and material validation tabs
- Add UI settings group in settings page (font selection, size, input width)
- For User users: automatically use shared Production IDs, simplified UI
- Apply font settings to input and log widgets
- Use sashpos() to set initial pane width correctly
