feat: check Tiny products and add a supervised order test

"Testar conexão" now also reads the four configured Tiny products and
requires each to be active. app/tiny_probe.py runs from the worker console
to list products, confirm the configured ids, and create one marked test
order through the worker's own delivery path, proving the duplicate guard
by search before a second delivery. Nothing is sent without --confirmar.
