Server instructions

Send real faxes to institutions (EU-focused). Flow: 1) upload the PDF via HTTP multipart to /api/upload (see the send_fax tool description), 2) call send_fax, 3) have the user pay the returned checkout_url, 4) poll get_fax_status until delivered or failed. Failed faxes are auto-refunded. With a prepaid API key on the connection (Authorization: Bearer stf_live_...) step 3 disappears: send_fax debits the credit balance and sends immediately; check_balance reports the remaining credit.
