TZGyn ef44ef7ac6 Let system dialogs take clicks during capture; hint Esc on the overlay
The event tap consumes every click while selecting, which made permission
prompts unclickable when they appeared mid-capture. Clicks now pass
through when a system dialog (SecurityAgent / System Settings) is
frontmost, and the overlay shows a visible Esc hint as an escape hatch.
