Add extra='ignore' to Settings Config to prevent ValidationError when
.env files contain deprecated variables (e.g., PADDLEOCR_MODEL_DIR).
This ensures backwards compatibility with Docker deployments.

Phase 1-3 implementation of extract-table-cell-boxes proposal:
- Add enable_table_cell_boxes_extraction config option
- Implement lazy-loaded SLANeXt model caching in PPStructureEnhanced
- Add _extract_cell_boxes_with_slanet() method for direct model invocation
- Supplement PPStructureV3 table processing with SLANeXt cell boxes
- Add _compute_table_grid_from_cell_boxes() for column width calculation
- Modify draw_table_region() to use cell_boxes for accurate layout
Key features:
- Auto-detect table type (wired/wireless) using PP-LCNet classifier
- Convert 8-point polygon bbox to 4-point rectangle
- Graceful fallback to equal distribution when cell_boxes unavailable
- Proper coordinate transformation with scaling support

- Fix parsing_res_list field mapping (block_label, block_content, block_bbox)
- Add fine-grained PP-StructureV3 configuration parameters
- Lower detection thresholds (0.5→0.2) for more sensitive element detection
- Use 'small' merge mode instead of default to minimize bbox merging
- Add layout_nms, unclip_ratio, text_det thresholds for better control
- Result: Doubled element detection from 6 to 12 elements on complex diagrams
