Align Jest devDependencies to v29, remove unused jest-environment-jsdom

[Copilot]

Root package.json mixed Jest v29 (jest) with Jest v30 internals (jest-environment-jsdom, jest-util), causing potential resolver/version skew in the lockfile.

Changes

• Removed jest-environment-jsdom@^30.3.0 — unused at root; jest.config.js sets testEnvironment: 'node'. Frontend owns its own correctly-pinned jest-environment-jsdom@^29.7.0.
• Downgraded jest-util ^30.3.0 → ^29.7.0 — required peer dep for ts-jest; must be at top-level and aligned with jest@^29.7.0.

Before:

"jest": "^29.7.0",
"jest-environment-jsdom": "^30.3.0",
"jest-util": "^30.3.0"

After:

"jest": "^29.7.0",
"jest-util": "^29.7.0"
