[c0ball]

I've updated the Next version from 15.5.7 to 15.5.9to mitigate the following CVEs:

• CVE-2025-55184 (high): DoS via malicious HTTP request causing server to hang and consume CPU
• CVE-2025-55183 (medium): Compiled Server Action source code can be exposed via malicious request
• CVE-2025-67779 (high): Incomplete fix for CVE-2025-55184 DoS via malicious RSC payload causing infinite loop

Greptile Summary

This PR updates Next.js from version 15.5.7 to 15.5.9 across three package.json files to mitigate three CVEs: CVE-2025-55184 (DoS via malicious HTTP request), CVE-2025-55183 (Server Action source code exposure), and CVE-2025-67779 (Incomplete fix for CVE-2025-55184). The changes are straightforward version bumps in the dependencies section of:

• apps/web/package.json - Updated Next.js dependency
• packages/database/package.json - Updated Next.js dependency
• packages/web-backend/package.json - Updated Next.js dependency

However, there is a version consistency issue: the eslint-config-next devDependency in apps/web/package.json remains at 15.5.7 and should be updated to 15.5.9 to match the Next.js version. The eslint-config-next package is versioned alongside Next.js and should be kept in sync for ESLint rule compatibility and to benefit from the same security fixes.

Confidence Score: 3/5

• The PR requires one critical fix before merging: the eslint-config-next version must be updated to match the Next.js version.
• The PR correctly updates Next.js to 15.5.9 in all three relevant packages to address security vulnerabilities. However, a critical consistency issue was identified: eslint-config-next in apps/web/package.json remains at 15.5.7 instead of being updated to 15.5.9. This versioned package should always match the Next.js version for ESLint rule compatibility and to ensure all security fixes are applied. The incomplete update reduces confidence from high to moderate.
• apps/web/package.json requires the eslint-config-next version to be updated from 15.5.7 to 15.5.9

Thanks for merging this PR so quickly @richiemcilroy ! Would it be possible to cut a 0.4.1 release that includes this fix?
