Factory console and customer order status: investor demo

New page docs/factory-console.html (site /demos/factory/): the factory
application of digital-factory.md on a simulated plant day, with a
switch to the customer portal of the same orders.

Factory console (sidebar: Floor, Orders, Quality, Lab, Metal, Ledger):
- floor: five presses of the launch fleet (two Newbilt Duplex systems,
  one Classic) with the mounted order, live good / rejected counters,
  stamper plays against life, cycle time and steam; KPIs for the day;
  live optical inspection stream with record keys; alerts (stops, lab
  holds, stampers near end of life, listening reviews, long gate waits);
  stations (cutting, galvanics, stamper prep, lab, packing); orders by
  stage; good records per day
- orders list with stage filters and search; order detail with stage
  track, approvals, metal genealogy and stamper metrology, press run
  telemetry, compound lot certificate, rejects by reason, audio samples,
  packing and shipping, and the order's events
- press detail with telemetry sparklines; quality (rejects by reason,
  yield per press, audio comparison); lab (compound lots with results
  against illustrative limits, one lot on hold with re-dry and retest,
  regrind batches, hoppers); metal (baths, mounted stampers, metrology,
  archive); hash-chained event log

Customer portal (four demo customers: pressing now, waiting to approve
the test pressing, in plating, delivered): progress through every step
and the three gates, copies pressed so far with the latest copies and
their record keys, approving the test pressing books the press slot
(greedy plan of the queue gives the start time and press), and a quality
report that fills in step by step: files, lacquers, metal parts with
metrology, test pressings, the compound lot's lab results, pressing and
inspection, listening checks, packing.

Simulation: 60 days warmed up at load (about 0.7 s), then 1x to 3600x.
Stages and durations from the production timeline, Newbilt cycle times,
two shifts 06:00 to 22:00, unplanned stops, stamper life 1,000 to 2,000
plays, audio sampling first-off plus about 1 in 50 (1 in 25 near end of
life), compound lots through the lab gate and release test pressing.
All orders, values and IDs are simulated; limits are illustrative.

(customer-facing view), the README and the landing page.
