🧪 [testing improvement] Add tests for Tailwind class merge utility

[hatimhtm]

🎯 What: The cn utility from lib/utils.ts was missing tests, preventing any regressions in case it needed updates or modifications later.
📊 Coverage: The test suite lib/utils.test.ts now covers the following scenarios:

• Basic concatenation of multiple Tailwind classes
• Conditional class inclusion using falsy/truthy checks
• Overriding of Tailwind classes
• Handling of complex inputs (arrays and objects)
  ✨ Result: Enhanced the codebase test coverage with tests capable of properly catching bugs. Also fixed minor linting and dependency array issues to ensure robust build.
