Prep for iOS 16 (#223)

• Don’t render spacer in iOS 16+

• Bump version and build for TestFlight

• Bump version and build of action extension

• Run SwiftLint on all files for each build

This prevents a build warning in Xcode 14 because SwiftLint doesn’t yet support input/output files for these script execution build phases. It’s fast enough, so running it on all files isn’t an issue.

• Add missing error handling on login view

• Clean up line_length warning

• Update change log
