fix: rely on XcodeGen native AppIcon.icon; harden patch fallback

Remove fileTypes icon override and explicit type:file so XcodeGen 2.37+
emits folder.iconcomposer.icon directly. Skip patch when native output is
valid; otherwise run patch v3 with broader PBX discovery and validation.

Fixes persistent 'AppIcon.icon entry has unexpected shape' on Xcode 26.
