Resolve material types for unknown filament vendors

[BenJule]

Summary

Resolve known material types even when a third-party tray reports a vendor that does not exist in the local preset collection.

Root cause

Material inference restricted candidate types to the reported vendor whenever the vendor string was non-empty. An unknown vendor therefore produced an empty candidate set and prevented otherwise recognizable material strings such as PETG HF from being parsed.

Changes

• use matching-vendor types when the reported vendor exists
• fall back to material types from all presets when it does not
• keep the original reported brand
• keep single-slot and batch inference behavior aligned

Validation

• TypeScript project check when local Node dependencies are available
• git diff --check
• one GPG-signed commit

No local full build was performed.
