Fixed some unreasonable aspects.

● Fixed the bug where the quality level of items crafted at the workbench was randomly initialized.

● If the materials required for crafting contain quality levels (e.g., firearm parts of different quality levels), then the crafted item's quality level will match that of the material items.
