Split adaptive value source into explicit adaptive_time and adaptive_scene types

Replace single "adaptive" type with adaptive_mode sub-selector by two
distinct source types in the dropdown. Removes the adaptive_mode field
entirely — the source_type itself carries the mode. Clearer UX with
"Adaptive (Time of Day)" and "Adaptive (Scene)" as separate options.
