Add pairwise cross-row column alignment check to find_table_regions_strict().
Real tables have fixed column X positions that repeat across rows (score ~1.0),
while paragraph text has varying word positions (score ~0.3-0.4). Regions with
average pairwise alignment score < 0.5 are now rejected.
Also remove the num_cols >= 5 content-check bypass for BodyFont mode, requiring
body-font tables to always have ≥30% data-like cell content.
Fixes false table detection across 9+ PDFs including AI_Cultural_Collections
(-730 false lines), 131212888 (-740), Data-Processing-Agreement (-108),
CEP_DN_Interest_Rates (-93). No regressions on legitimate tables.

Tables at body font size were invisible because detect_tables() gated on
font_size <= base * 0.90. Add a second pass with stricter structural
criteria (3+ columns, 70% alignment, 3+ rows with 3+ X-clusters) to
detect body-font tables without false-positiving on paragraphs. Also
raise the row limit from 30 to 50/100 to support large data tables.
