Fixes #64725

Analysis

Under --noLib, missing-global diagnostics can resolve import aliases before globalObjectType is initialized. The property lookup used to refine the type-as-namespace error then dereferences nil:

interface C {}
import x = C.m;

Fix

• Guard the property-specific diagnostic lookup until globalObjectType is available; otherwise report the ordinary type-as-namespace error.
• Add the minimal reproducer and diagnostic, emit, type, and symbol baselines.
