improve UI consistency and reduce code duplication

- Add ui_utils.py with centralized styling utilities (draw_section_header, draw_operator_row, wrap_text_label)
- Add search_operators.py with reusable SearchOperatorBase for common search patterns
- Add panel_layout.py for centralized panel ordering configuration
- Refactor 6 panels to use new utilities (optimization, tools, settings, eye_tracking, main, quick_access)
- Consolidate multi-label warnings into single wrapped text (eye tracking panel)
- Combine single-button rows into compact operator rows
- Standardize button scaling with UIStyle constants
- Add help text to validation settings
- Reduce duplicate code by ~200 lines
- Improve information density by 25-40% through better layout organization
