fix(native): correct PKEY_AppUserModel_ID import (D6 CI build)

Windows CI failed: PROPERTYKEY is not in Win32::UI::Shell::PropertiesSystem.
Use the ready-made PKEY_AppUserModel_ID constant from Win32::Storage::Enhanced
Storage (same module jumplist.rs uses for PKEY_Title, feature already enabled)
instead of hand-rolling the PROPERTYKEY — drops the GUID::from_u128 dependency.
Also simplify IPersistFile::Save's fremember arg (it's bool, not BOOL).

All windows-crate symbols now verified against windows-docs-rs (PKEY_AppUser
Model_ID / IPersistFile::Save / SetCurrentProcessExplicitAppUserModelID /
CreateToastNotifierWithId).
