test(17-11): add GlobalImageHistory component tests

- Test empty state rendering (returns null when no history) - Test trigger button with count badge and title - Test fan open/close toggle functionality - Test max 10 items in fan view with overflow indicator - Test sidebar display with all history items - Test Clear All functionality calling clearGlobalHistory - Test model display (Pro vs Standard labels) - Test prompt display with truncation and empty state - Test drag and drop with proper data transfer - Test relative time formatting (just now, minutes, hours) - Test image thumbnail rendering in fan and sidebar - Test keyboard navigation (Escape to close) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
