fix issue where generic support for pla inherits bbl behaviour

[ratdoux]

概要

修复 Snapmaker Web 打印预处理页中，Generic Support For PLA 被发送为 PLA-S 导致耗材匹配失败的问题。
保留使用 full_print_config() 生成完整、与颜色槽位对齐的耗材类型列表。
在该 Web 匹配接口中使用原始 filament_type，避免把 Snapmaker 耗材映射成 Bambu 风格的 PLA-S / PA-S 支撑耗材类型。

原因

get_filament_type() 会把带有 GFS00 / filament_is_support 的支撑 PLA 规范化为 PLA-S，但 Snapmaker 设备端并没有 PLA-S 这种挂载耗材类型。
因此 Generic Support For PLA 在切片配置中是支撑耗材，但设备端实际只会上报 PLA，导致打印预处理页出现耗材类型不匹配。

Summary

Fix Snapmaker web preprint filament matching when Generic Support For PLA was sent as PLA-S.
Keep using full_print_config() so the filament type list remains complete and aligned with filament/color slots.
Use the raw configured filament_type in this web matching payload to avoid sending Bambu-style support tokens such as PLA-S / PA-S to Snapmaker devices.

Why

get_filament_type() normalizes support PLA with GFS00 / filament_is_support into PLA-S, but Snapmaker devices do not expose PLA-S as a mounted filament type.

Generic Support For PLA is a support filament in the slicer config, while the device reports the mounted material as PLA, which caused the preprint matcher to reject an otherwise valid mapping.
