🧪 [Add ContentView UserDefaults tests]

[hatimhtm]

🎯 What:
Missing unit tests for ContentView. Testing SwiftUI views directly can be complex, but we can verify the underlying logic, specifically its interaction with UserDefaults.standard.

📊 Coverage:

• Added ContentViewTests.swift inside a new Click2MinimizeTests/ directory.
• Test coverage for ContentView default state (when UserDefaults does not have a value).
• Test coverage for ContentView with existing UserDefaults set to true.
• Test coverage for ContentView with existing UserDefaults set to false.

✨ Result:

• Increased test coverage for ContentView.
• Verification that defaults are handled correctly and logic functions as expected.
