fix(frontend): merge duplicate path imports in eslint config

[Shubb07]

Resolves #3266

This PR fixes the SonarCloud issue where the path module was imported multiple times in frontend/eslint.config.mjs by merging them into a single import.

This removes the javascript:S3863 code smell and improves maintainability.
