…al layer 2 transition In mixed-material prints (e.g. PLA at 65°C + TPU at 35°C), the bed temperature was set using only the first extruder's 'other layers' value. When the first extruder happens to be the lower-temp material, the bed drops on layer 2 and causes adhesion failures for the higher-temp material. Fix by iterating all active extruders and taking the maximum bed temperature.

Summary
In mixed-material prints (e.g. PLA at 65°C bed + TPU at 35°C bed), the bed temperature was set using only the first extruder's "other layers" value on the layer 2 transition. When the first extruder is the lower-temp material (TPU), the bed drops to 35°C on layer 2, causing adhesion failures for PLA.
Fix by iterating all active extruders and using the maximum bed temperature.
Closes / supersedes #332.
