docs(wiki): USB printer cover-open field bug writeup; add art-docker-station lab box

Printer investigation (park-buzi): cover-open on the USB thermal
printer wedges its status offline/faulty, surviving a full reboot,
recoverable only via `docker restart server`. Traced sendRawUsb/
probeUsb end-to-end — no persistent handle in the app layer, so the
leading theory is the container's /dev/usb directory bind-mount
retaining a stale view across the printer's physical re-enumeration.
Not yet confirmed on hardware; documented with repro/confirmation
commands and ranked candidate fixes.

Also registers a new lab bench box, "art-docker-station", as a Komodo
Stack (dev tier, same shape as park-lab, its own isolated secret refs).
