🧪 test: Add tests for DumpCommand handle method

[juzaweb]

🎯 What: The testing gap addressed
This PR addresses the missing unit tests for the handle method in DumpCommand.php.

📊 Coverage: What scenarios are now tested

• When a specific module argument is provided (module:dump Blog), ensuring dump is called with that module.
• When no module argument is provided (module:dump), ensuring dumpAll is called.

✨ Result: The improvement in test coverage
DumpCommand handle method is now 100% tested with robust mock integration, reducing risk when making changes to the module dumping process.
