fix: Resolve react-scripts-related vulnerability by applying package …

…overrides

- Moved `react-scripts` to `devDependencies` to mitigate dependency conflict with `nth-check`.
- Applied overrides to update `nth-check` to a non-vulnerable version (>=2.0.2).
- Updated `postcss` to match the required version (>=8.4.31) in `react-scripts`.
- Adjusted package-lock.json to remove old references to vulnerable packages.
