Summary of Changes

Hello @HoseokWon99, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

I've implemented a fix that standardizes how range parameters are handled across the API. This primarily involves switching the expected delimiter for range values from a comma to a hyphen. Additionally, I've cleaned up some unused code related to an IsPair decorator and enhanced the RangeObject with better Swagger documentation and validation decorators.

Highlights

• API Parameter Pattern Change: Updated API parameter patterns for age and experience to use a hyphen (-) as a separator instead of a comma (,) for range values, ensuring consistency in API input.
• IsRange Decorator Update: Modified the IsRange decorator to correctly parse range strings using a hyphen (-) as the delimiter and removed a redundant Matches validation, streamlining the range parsing logic.
• Code Cleanup: Removed the IsPair decorator and its corresponding file, indicating it was no longer needed, which helps in code cleanup and reduces bundle size.
• RangeObject Enhancement: Enhanced the RangeObject class with @ApiProperty, @IsNumber, and @IsOptional decorators for better Swagger documentation and validation of its lower and upper bounds, improving API clarity and robustness.

Code Review

This pull request updates the range separator in API queries from a comma to a hyphen. It also removes an unused IsPair decorator and improves the RangeObject DTO with validation and API decorators. While the changes are generally good, I've found a critical issue in the custom IsRange validator. The validation logic is flawed and allows invalid input to pass, which could lead to unexpected behavior. My review includes a specific suggestion to fix this vulnerability.
