Update platform configuration

Update platform configuration settings. cardConfigs can establish platform-level per-transaction and UTC-calendar-day card caps. Grid enforces the lower of each platform cap and its corresponding card-specific value without replacing the card-specific value. Daily limits reset at 00:00 UTC.
