Code Review

This pull request from Snyk upgrades the express package from 4.17.1 to 4.22.1. This is an important security update that resolves several vulnerabilities, including some with high severity. The changes in package.json and package-lock.json are correct for this upgrade.

While the PR itself only updates dependencies, I noticed in src/server.ts that the body-parser package is still being used directly (app.use(bodyParser.json())). Since Express v4.16.0, this middleware is included with Express as express.json(). I recommend creating a follow-up ticket to refactor this usage to app.use(express.json()) to align with current best practices.

The changes in this PR are safe to merge and are recommended for security.
