Support Landscape orientation for Assurance screens

[prudrabhat]

Actual Behaviour

Assurance 3.x UI currently switches to portrait mode irrespective of the current orientation and then switches back to the original orientation of the host app. This was done because majority of the usage is in portrait mode and designing the UI to be adaptive for both portrait and landscape modes did not align with 3.x release.

Expected Behaviour

Display the Assurance screens in the host screen orientation.

Steps to Reproduce

Switch to landscape mode on a device and launch Assurance. Notice that the Assurance screen orientation is in portrait mode.

Platform and Version

Assurance 3.x, all devices.
