Fix Guide: Tahoe Menu Bar Icons Disappearing

Symptom: After using an external display or switching resolutions on macOS Tahoe, some menu bar icons (Control Center, Clock, or 3rd party apps) become invisible or truncated.

Why this happens

Tahoe's new dynamic spacing for the notch can cause the SystemUIServer to miscalculate the available width for menu extras, leading to them being pushed off-canvas.
