jcoffey-dev f6c228b87c Add two storefronts, a payment gateway, and alerts worth waking up for
The estate could show an operator their infrastructure and had nothing to
say to the business paying for it. Two storefronts and the gateway behind
both fix that: Magento on two hosts, WooCommerce on one, and pay-01
carrying authorisations with amount, gateway and decline reason. Orders,
revenue, average order value, where checkout loses people and why a card
was refused now come out of the same log lines the operators are already
reading, which is the argument for not running a separate metrics stack
beside this one.

Two platforms rather than one deliberately. Magento and WooCommerce write
about the same events differently, so a panel that groups by service
instead of assuming a single shape is the honest way to build one -- and
the demo shows that rather than describing it.

Order totals are built from a basket of real SKUs at real prices rather
than drawn from a distribution, so average order value moves the way one
actually moves. Declines rise during the seeded outage window alongside
the 5xx rate, because whatever fails requests fails authorisations too.

Twenty-seven new alert rules, thresholds calibrated against what the
fleet actually emits -- measured on the demo's own week of history rather
than guessed. A rule set at the average fires constantly and one set an
order of magnitude above it never fires; these sit two to three times the
steady-state rate, so they are quiet in normal operation and true during
the diurnal peak or the seeded incident. Four are absence rules, because
a domain controller or a storefront going silent is not a threshold
question.

Six new dashboards: fleet health, golden signals, security posture,
capacity and storage, commerce, payments.

Three limits of the query language found the hard way and worth writing
down, because each was discovered by a panel failing rather than by
reading: `dc()` does not exist -- the functions are count, sum, avg, min
and max; `or` is not supported between structured filters, so a panel
spanning tiers filters on the attribute they share and groups by service;
and dashboards refuse raw SQL outright. The validator run over all 169
panels and 38 rules now checks every one of those, plus stages, viz types
and comparators.
