Fix LaTeX compilation errors in GitHub Actions

Remove problematic custom table templates from XSL that were causing
incomplete \ifx conditionals in LaTeX output. The templates were
interfering with dblatex's default table processing.

Table improvements will rely on the enhanced preamble.tex packages
and post-processing script instead.
