Pollution Absorber: Improved 1.0.2

Compact, taller air-filter cabinet without an access door. The top fan and housing now share the same sprite anchor. The indicator is red without fuel and green while working.

Validated in an isolated four-sided inserter scene, the New_clean save (3,600 ticks), and base Factorio without DLC. Absorption code and collision geometry are unchanged from 1.0.1.
