The DB configJson uses different field names than wizard types expect
(e.g., deterministic.rules vs rules, votingEnabled vs juryVotingEnabled).
The ?? operator only guards null/undefined, but configJson is {} (truthy),
so defaults never applied. This caused config.rules.map() to crash with
"Cannot read properties of undefined (reading 'map')".
Fix: spread defaults first then overlay DB values, and add defensive ??
fallbacks in all section components for potentially undefined properties.
