fix(para_split_v3): refine list block detection in paragraph splitting

- Update list block detection logic to require at least 2 numeric start lines
- Ensure the number of numeric start lines matches the number of end lines
- Remove detection of non-border starting lines for simplicity

refactor(para_split_v3): merge list and index block detection

Increased the threshold for filling spans in blocks from 0.3 to 0.5 to improve the accuracy of block formation. This change helps refine the grouping of spans into blocks, potentially enhancing the overall structure and readability of the PDF content.

- Combine __is_list_block() and __is_index_block() into a single function __is_list_or_index_block()
- Simplify block type determination logic
- Remove redundant code and improve readability
- Optimize block merging process

Add List and Index to the list of block types being processed in the draw_bbox.py file. This inclusion ensures that these block types are handled similarly to other text-containing blocks, improving the overall document processing accuracy and consistency.

feat(list&index block): detect and merge list and index blocks

- Add detection for list and index blocks in OCR processing- Implement merging of list and index blocks across pages
- Update block types to include list and index categories
- Adjust text merging logic to handle new block types
- Modify layout drawing to distinguish list and index blocks
