Replace 14 TemplatableValue fields with a per-field union that stores either a constant value or a callable pointer in the same 4 bytes (on 32-bit targets). A 2-bit-per-field type tag in a uint32_t tracks field state (unset/constant/stateless lambda/stateful lambda). Reduces LightControlAction from 128 to 76 bytes per instance on ESP32. For a config with 8 light actions, this saves 416 bytes of RAM and 476 bytes of flash (from eliminated TemplatableValue template instantiations).
