Security: Address npm audit vulnerabilities

[mcottontensor]

This PR resolves several security vulnerabilities identified by npm audit.

Changes

Dependency overrides (root package.json)

• Added a global cross-spawn >=6.0.6 override to address a high severity ReDoS vulnerability (GHSA-3xgq-45jj-v275) present in pre-commit's pinned version
• Broadened the existing glob override from a fs-routes-scoped fix to a global override, simplifying the configuration
• Retained existing serialize-javascript and tar overrides from the previous dependabot fixes

Frontend library (Frontend/library/package.json)

• Upgraded jest-environment-jsdom from ^29.7.0 to ^30.3.0 to resolve a vulnerability in the older version

Also includes the prior commit addressing dependabot issues in tar and express-rate-limit.
