Deploy Ladill POS / deploy (push) Successful in 56s
Replace ad-hoc demo-cashier-{id} accounts with DemoWorld staff who hold
a pos role, mirrored locally by email until SSO remaps to public_id.
Sales for the first named customers now use DemoWorld people (name +
phone) instead of generic "Cash Customer N" labels, and staff logins
skip the login reseed so mid-demo state survives.
