[e2e] Create an iPad suite

[unlikelyzero]

Summary

We have best effort support for iPad devices. We should add some testing to our e2e suite.

Notes on Open MCT Mobile

The biggest difference between the ipad suite is the lack of a create button.
The most important displays or domain objects to focus on will be

• notebooks
• plots

Mobile-specific things to test

The mobile-specific things we will need to test:

• "mobile touch" works with interactive elements like the search bar
• screen orientation changes

Execution

In no particular order:

• Determine the exact iPad devices which will be used during the mission. Update our project in playwright-*.config.js
• Update existing test suites which do not need domain objects (like timeConductor) to support
• Add a new test suite which tests mobile-specific things like screen orientation change
• Investigate a visual testing suite. It's possible that percy's DOMSnapshot publishing would override the mobile view.
• Update our CI such that this only runs once per platform. Since this is an emulator/simulator, there's no reason to test this on macOS, Windows, and Ubuntu
• Run the iPad view on the nightly with at least one test suite (smoke)
