When a user uploads media for the first time and hasn't already configured the optimization settings under App Settings, we display a popup. The popup informs them that image optimization is enabled by default, and allows them to turn that setting off if they'd like to.

Optimization popup	Default App Settings

Whether or not the popup displays is determined by the shouldAdvertiseImageOptimization() function.

We already have OptimizeMediaUseCaseTest.kt, which is used in AddLocalMediaToPostUseCaseTest.kt to check images are optimised depending on if the setting’s on or off, amongst other relevant workflows. It would be nice to add some additional tests to ensure the setting is on by default for fresh installs, as well as to check that the popup displays in the specific scenarios it's mean to.
