Added: Ability to Uninstall the App

[Sewer56]

This PR migrates the remaining code related to removing loadouts and app uninstallation.

• ✅ Uninstall script runs on Windows.
• ✅ Uninstalling with App Running on Windows (files in use) runs as intended.
  • On Windows, it kills all app instances and performs a manual cleanup via dynamically generated powershell script.
  • The powershell code written should be trivial enough that even 15+ year old versions of it should run it fine.
• ✅ Adds missing install and uninstall icon.
• ✅ Uninstalling deletes whole DataModel directory and...
  • Configured Logging Location
  • MnemonicDB Path
  • File Extractor Temp Folder
  • Logger base folder
  • Default Config folder for JSON Settings Storage backend
  • All archive locations where user has decided to store .nx archives.

I've tried to be comprehensive with the locations deleted, removing our defaults as well as any paths that are configurable. (Even if they are not yet exposed via the Settings UI!!). After deletion, no files of notable size should hopefully be left over on disk.

Note(s)

• Still need to wait for upstream https://github.com/kuiperzone/PupNet-Deploy/pull/36 to merge the necessary changes to PupNet.
