Fix Adaptive mode not restoring lighting conditions

The blueprint was unconditionally overriding use_defaults to 'current',
preventing modes from specifying their own use_defaults value. This caused
Adaptive mode (which uses use_defaults: 'configuration') to keep the current
settings instead of resetting to configuration defaults.

Modified the data template to conditionally add use_defaults: 'current' only
when not already present in al_config, allowing modes like Adaptive to use
their specified value while maintaining backward compatibility.
