fix(tables): Detect dense body-font tables and fix table-only page rendering

Browse Source 
Raise BodyFont max_rows from 100 to 200 so tables with ~115 rows
(like the Closed Business Accounts PDF) pass validation. Add date
pattern recognition (MM/DD/YYYY, YYYY-MM-DD) to looks_like_table_data()
so date columns count toward the 30% data threshold.

Fix a bug where pages whose text is entirely consumed by tables
produced empty output — the post-loop cleanup only checked
current_page (stuck at 0), missing all table content. Now iterates
all pages with uninserted tables/images.
