feat: add create_file_from_elements() to re-create document files from elements (#4259) ## Summary Adds `create_file_from_elements()` in `unstructured.staging.base` so users can re-build a document file from a list of elements (reverse of partition). Supports the workflow: partition -> modify elements (e.g. replace Image with NarrativeText using alt text) -> write back to file. Closes #3994. ## Changes - **`unstructured/staging/base.py`**: New `create_file_from_elements(elements, format="markdown"|"html"|"text", filename=None, ...)` that delegates to `elements_to_md`, `elements_to_html`, or `elements_to_text` and optionally writes to a file. - **`test_unstructured/staging/test_base.py`**: Tests for markdown, text, and HTML output and for unsupported format raising `ValueError`.
