FX.21 Account: a certificate whose MeCentral link fails opens a support ticket

Owner 2026-11-04: if the MeCentral link can't be obtained, open a support ticket, never show the local version. The broker cron now opens one ticket in /admin/messages (topic Licensing, with the member's address) for a filing that is held, rejected, filed with no document id, or unanswered after a day. Expected refusals (address not verified, not permitted, test fixture, account gone) open none. The member gets no acknowledgement mail; the /account card says 'We opened a support ticket for this' with no link, until the filing succeeds. No filing was failing when this went live, so no ticket has been opened on a real account yet.
