docs(wiki): record the two configured printers (Cashino at lane, Rongta at booth)

The rongta-printer "Deployment" section still described a single
2026-06-14 unit. The live site now runs two: entry-dispenser 10.0.10.9
(Cashino, `cashino` ping-only driver) and booth-receipt 10.0.10.10
(Rongta, full status-page monitoring). Follow-up to 3e6773a.
