The original test seeded the DB with the schema default (1) and asserted
the response was true after a partial PATCH. That passes both for
'untouched' and 'reset to default' — doesn't distinguish them. Now the
test toggles the DB column to false BEFORE the PATCH, then asserts the
false value survives both in the response AND in the DB row directly.
Surfaces the federatedRegistrationOpen flag (Task 1 schema column) on the
admin settings GET/PATCH endpoints and the public /api/instance/info
endpoint. Closes the 3 deferred TypeScript errors from Task 2 by
populating the now-required InstanceAdminSettings/InstanceInfoResponse
field.
Adds smoke tests (routes/instance.test.ts, routes/settings.test.ts) that
lock in the JSON contract the Connections UI (Task 21) and admin
RegistrationPanel (Task 15) consume, plus boolean-validation coverage
for the PATCH path. Updates docs/systems/admin.md with the new field in
both InstanceAdminSettings and the public info response schema.
