Pull Request Overview

This PR adds a new utility function checkHttpUrl to the validationUtil module for validating HTTP/HTTPS URLs. The implementation uses a two-step validation approach: first checking the protocol with a regex pattern, then using the native URL constructor for complete validation.

• Adds checkHttpUrl function with regex pre-validation and URL constructor validation
• Comprehensive test coverage with 16 test cases covering valid and invalid URL scenarios
• Exports the new function from the validationUtil module
