/**
 * MxChat Licence Check — asks mxchat.ai whether this site's domain is still
 * switched on for its licence key, and honours an explicit "off" from the
 * licence holder's My Account after a three-day grace period.
 *
 * Plan: plan-mxchat-20261007-c93ede (Support Ticket 467). An Agency licence
 * holder who resells to clients could see the domains activated on a key but
 * had no way to switch one off, and even a server-side unlink left the old
 * install running Pro: `mxchat_license_status` is a local option written at
 * activation and never re-checked.
 *
 * The rules, from Maxwell's approval note (they override the original spec):
 *
 *  1. Turning back on is immediate. A site that is off (or in its grace
 *     period) re-checks when an admin opens any MxChat screen, at most once a
 *     minute; on the "Check license now" button; and hourly in the background.
 *     Activating from the site's own Activate button stays instant as before.
 *  2. A site that is on checks once a day, at a random time per site.
 *  3. ONLY AN EXPLICIT "OFF" COUNTS. A timeout, a 5xx, a non-JSON body, a DNS
 *     failure or an mxchat.ai outage never switches a site off. Today's
 *     production endpoint does not know this route yet and answers
 *     {"success":false,"data":"Invalid action"} — that is an error here too,
 *     so a core shipped ahead of the website change keeps every site on.
 *  4. A site move is not "off". A valid key on a domain mxchat.ai does not
 *     recognise ("unknown") stays on.
 *  5. Grace period: after the first explicit off the admin sees a notice and
 *     Pro is switched off only when an off answer arrives three days after the
 *     first one with no on/unknown in between. Nothing else is touched:
 *     settings, knowledge, the saved key and email, and the free features all
 *     stay exactly as they are, so switching back on restores Pro in place.
 *
 * What is sent to mxchat.ai: the licence key, the account email, the site's
 * host name and the plugin version (the same three identifiers the existing
 * activate / deactivate / check-domain calls already send, plus the version).
 * The readme's "External services" section documents all four calls.
