refactor(pdf): switch AWB template to landscape orientation

Update the AWB document generation to use landscape mode and adjust
the layout to utilize the additional horizontal space.

Key changes:
- Change `PdfService` orientation from portrait to landscape for AWB.
- Refactor `awb.blade.php` to use a side-by-side layout for terms
  and signatures.
- Adjust grid column widths from 50% to 25% to accommodate the
  new orientation.
- Update `@page` margin definitions for better print alignment.
