Fix useExtraContentPadding tests by removing jest.resetModules and dynamic require

jest.resetModules() was causing React to be reloaded, creating multiple React
instances and violating the Rules of Hooks. The tests used top-level
jest.mock() which doesn't require module resetting between tests - the mock is
already applied globally. The dynamic require pattern was cargo-culted from
useChatKeyboard tests which use jest.doMock() and legitimately need
jest.resetModules(), but it served no purpose here and was actively harmful.
