officer kiosk is the product name; OAS was a placeholder that mimicked expo's
application services and is gone.
the rename is total because nothing has shipped: appName, permission key, all
four table prefixes, every index and check constraint name, the exported drizzle
symbols, and the secret-store purpose. no rows exist anywhere, so there is no
migration and no compatibility window - which is exactly why doing it now cost
nothing and doing it after the first publish would have cost a manual migration
on every install.
the one remaining mention of OAS is dated history in the manifest, naming what
this was ported from.
