design: test-email - the Test message card in the right stack

Health's left stack is one polled element (health_stack, swapped whole
every refresh): a form there would lose the address being typed. Card 09
moves under Configuration, the right stack's static end, as Configuration
itself sits outside the poll for its button. On a phone the cards keep the
order of their numbers (data-order). outlines.json rewritten for health.
