Gehl 1085 Forage Harvestor v1.0.0.5

Updated the Gehl 1085 pack for Farming Simulator 25 compatibility and cleaned up several XML/resource issues found during testing.

Main fixes:
Added/fixed missing store/icon image references so the mod no longer looks for a missing 1085icon.png.
Updated the mod descriptor/versioning for FS25.
Cleaned up outdated FS22-style XML entries that FS25 no longer supports.
Fixed old PTO material/color attributes by moving them toward FS25-supported material template behavior.
Corrected invalid pipe/rotation limit values that were causing XML parse warnings.
Added the missing FS25 collision/fillable bit for the additive tank fill root.
Updated the Gehl 1085 forage harvester converter setup so headers can properly match the chopper.
Fixed the Gehl Grass Pickup header compatibility so it uses the proper pickup-header converter setup.
Fixed the other header, TR330, so it uses the forage harvester converter setup instead of mismatched/old header behavior.
Repacked the mod as a clean updated zip, ending with the current test build:
FS25_Gehl1085_1_0_0_5_fixed.zip
Added a hidden 100 L forage buffer to the Gehl 1085, so:
When it has no valid wagon/trailer to unload into, that buffer should fill and force the chopper to stop harvesting instead of continuing with nowhere to put crop.
