fix(ui): sync functions now show actual current values instead of 沿用当前配置

- syncCashOnlyExecutionForAccount: reads entry.cash_only_execution, shows 是/否
- syncOptionOverlayForAccount: reads entry.option_overlay_enabled, shows 开启/关闭
- syncIncomeLayerForAccount: reads entry config, shows enabled/disabled

Previously all three defaulted to 'current' dropdown option without
showing the actual configured value.
