fix(test): bump jest-environment-jsdom to 30.4 to match jest

Every test suite was failing with:

    TypeError: this._moduleMocker.clearMocksOnScope is not a function
      at Runtime.resetModules (jest-runtime/build/index.js:3782:28)

Root cause: jest@30.4.0 ships jest-runtime@30.4.0 which calls
moduleMocker.clearMocksOnScope, but jest-environment-jsdom@30.3.0
provides jest-mock@30.3.0 in which that method does not yet exist.
Bumping jest-environment-jsdom to ^30.4.1 aligns its jest-mock with
jest-runtime's expectations and unblocks the suite (12 passed, 32 tests).
