fix: add jest-dom import back with ESLint disable for working tests

Integration tests require @testing-library/jest-dom for matchers like toHaveTextContent().
Added back with proper eslint-disable-next-line comment to resolve import/no-extraneous-dependencies.

Verified both test files now pass locally:
- Unit test: 30/30 tests passing
- Integration test: 11/11 tests passing
