V45.38: suppress iZotope 0x7E dialog

- _is_vst2_dll: pure-Python PE export-table check (magic-aware dd offset
  PE32+112) -> IZOzone11Core.dll (runtime lib, no VSTPluginMain) dropped
  from VST2 lists in _scan_plugins and list_scan_all; plugins.py same.
- _hidden_desktop_startupinfo: scan subprocess runs on hidden desktop
  (user32 CreateDesktopW, HDESK restype) -> third-party MessageBox invisible.
- SetErrorMode(SEM_FAILCRITICALERRORS|SEM_NOOPENFILEERRORBOX) in all 4
  bridge mains: missing dependency DLL fails silently instead of blocking.
