test: restore autofocus semantics in focused-element write tests

Remove explicit focus() calls from 'into focused element' and 'should
enter emoji char into focused element' tests. These tests verify that
write() targets the element with default/autofocus, not one explicitly
focused via focus(). The waitForNavigation: true in beforeEach is
sufficient for CI stability (confirmed by 17 consecutive green runs).

focus() is kept in the hideText block where it is necessary alongside
beforeEach goto() to ensure the element exists on a fresh page.
