fix: improve PDF sample data table rendering for wide datasets (#48)

* fix: improve PDF sample data table rendering for wide datasets

Changed sample data tables to use landscape orientation with smaller
font size and word wrapping to prevent column cutoff. Tables now use
6pt font with word-wrap and render in landscape mode for better fit
on datasets with many columns.

* fix: use compact table layout instead of landscape for sample data

Switched from landscape orientation to portrait with smaller font (5.5pt)
and table-layout fixed with word wrapping. This keeps pages normal size
while still fitting all columns properly.
