fix: restore confirm-password autocomplete regression test

PR #195 accidentally deleted the def line for
test_register_page_confirm_password_has_autocomplete, collapsing its
body into test_register_page_shows_password_requirements and demoting
its docstring to a no-op string statement. This restored the issue #156
autocomplete check as its own test.
