Deploy Ladill POS / deploy (push) Successful in 46s
Add public token-gated kitchen display for POS devices.
Kitchen display devices open a full-screen KDS without staff login,
with feed/stream/bump over the device token. Shared kitchen board
logic is extracted so the signed-in Kitchen page stays in sync.
