Use environment appName instead of hardcoded Loop

[marionbarker]

1. Add code needed to use environment that ties appName to CFBundleDisplayName
2. Use the appName from the environment to replace hardcoded Loop in strings
   • For one file, I did not know how to insert the environment variable for appName, so I put in a work-around string instead
   • This can be updated if someone provides instructions (PumpOpsSession.swift)

None of these changes could be tested.

• I think some of these views just aren't used anymore
• The one that is used requires an MDT with MySentry to test and I only have an MDT

@Environment is generally used on a SwiftUI view (this is an extension on a UIKit View controller), as the data is passed through the view hierarchy. I'm not sure how/if this is working?

I prepared code to use appName based off a few hints. I am working via "prototype example" and don't have a solid understanding of how and why it works. Your comment above that "@Environment is generally used on a SwiftUI view (this is an extension on a UIKit View controller)" probably indicates this will not work for MinimedKitUI/RadioSelectionTableViewController.swift as desired.

I was not able to test the modification for this file because I do not have a Medtronic pump that supports MySentry. I was able to test the other instances and show that they did work as expected.

There was a case for OmniBLE/Kit (BeepPreference) where the attempt to use appName did not succeed. See this link:

• Use environment for appName and replace hardcoded Loop with appName OmniBLE#120 (comment)

To summarize tests done in that PR: "To reiterate the problem, this picks up the defaultValue from LoopKit instead of the appName from the environment that I expected."

In that case, I demonstrated that whatever value was found on this line in LoopKit/LoopKitUI/Extensions/Environment+AppName.swift is what is inserted into appName when I tried to use it.
