Pass the `lang` parameter to `custom_model_init` in `doc_analyze` to support language-specific OCR configurations. This enhancement allows the use of language information to improve OCR accuracy when processing PDFs.

Refactor the pdf_extract_kit module to utilize a singleton pattern when initializing
atomic models. This change ensures that atomic models are instantiated at most once,
optimizing memory usage and reducing redundant initialization steps. The AtomModelSingleton
class now manages the instantiation and retrieval of atomic models, improving the
overall structure and efficiency of the codebase.

Removed the previously used gradio and gradio-pdf imports which were not leveraged in the code. Also,
replaced the custom `show_pdf` function with direct use of the `PDF` component from gradio for a simpler
and more integrated PDF upload and display solution, improving code maintainability and readability.

Previously, small blocks that overlapped with larger ones were merely removed. This fix
changes the approach to merge smaller blocks into the larger block instead, ensuring that
no information is lost and the larger block encompasses all the text content fully.

Reduce the span threshold used in fill_spans_in_blocks from 0.6 to 0.3 to
improve the accuracy of block filling based on layout analysis.
