This update reorganizes how WhatsApp and VoIP identify internal users by moving that logic to the user model. It should make the behavior more consistent across related communication features, with no expected change for day-to-day users.

Enterprise counter-part.

This update clarifies which automated test steps intentionally move users to a new page. It helps make testing more predictable across appointment, documents, helpdesk, point of sale, ecommerce, planning, and signing workflows, reducing false test issues without changing day-to-day user behavior.

In this commit, we add willUnload to steps that require it to
explicitly declare that the step will cause the page to be unloaded.
