Security vulnerabilities and automated fixes for nodejs security issues

A critical security issue was discovered in the S3 Express deployment configuration file where an AWS Secret Access Key was hardcoded as a placeholder example. This vulnerability could allow attackers to gain unauthorized access to AWS resources if the example file was accidentally deployed to production or committed to version control without proper sanitization.
A Node.js authentication service exposed unauthenticated OTP endpoints without adequate rate limiting, allowing attackers to exhaust email service quotas through repeated requests. The fix implements per-session resend caps and cooldown enforcement to prevent email-based denial of service attacks while preserving legitimate user workflows.
A GitHub Actions workflow in Node.js was storing authentication tokens in plain variables without masking them in logs, creating a critical security risk. When debug mode was enabled or errors occurred, tokens could be exposed in console output and GitHub Actions logs. The fix uses the `setSecret()` API to automatically mask sensitive credentials throughout the execution.
A missing cooldown period in Dependabot configuration creates a supply chain vulnerability by allowing automatic updates to newly published packages that could be malicious or unstable. This fix adds a 7-day cooldown to the `.github/dependabot.yml` file, ensuring newly published package versions are vetted before being proposed for update. This is critical for Node.js libraries where vulnerabilities affect all downstream consumers.
