- Upgrade Node.js requirement to >=24.0.0

FEATURES:
- Upgrade Vitest to 4.0.13 with improved testing capabilities
- Update all vitest-related packages (@vitest/ui, @vitest/coverage-v8)
- Upgrade react-syntax-highlighter to 16.1.0
- Update node-cron to 4.2.1
- Update lucide-react to 0.554.0

SECURITY:
- Resolve glob command injection vulnerability (CVE) via v10.5.0
- Fix all npm audit vulnerabilities (0 vulnerabilities found)
- Update prisma/client to 6.19.0
- Update all dependencies to latest secure versions

FIXES:
- Configure next.config.js for webpack with proper server-side module handling
