fix(login): keep remember-password toggle interactive in draggable header

The login shell sets -webkit-app-region: drag on its frameless header,
which captured clicks on the "记住密码" checkbox before v-model could
update. Mark .options-row and its descendants as no-drag, and bind the
checkbox via :checked + @change so the click reliably reaches the
toggle handler.
