This update refreshes how Odoo works with PDF files across delivery, documents, payroll, and signing features. It keeps these workflows compatible with the newer PDF library version without changing the intended user experience.

This pull request updates internal automated tests across several Odoo Enterprise apps so they align with upcoming changes in the shared testing framework. It should not change day-to-day product behavior, but helps keep future upgrades smoother and reduces maintenance risk.
