Upgrade Jest to v29.7.0 to fix test environment issues

- Upgrade from Jest 27.5.1 to 29.7.0 to match webamp package version
- Add jest-environment-jsdom as direct dependency
- Fixes 'Cannot read properties of undefined (reading testEnvironmentOptions)' error
- pnpm's stricter isolation revealed version conflicts between packages
- Tests now run properly but some snapshots need updating due to format changes
