fix(v1): use ASCII screenshot annotation to avoid garbled text

Browse Source 
cv2.putText only supports ASCII (Hershey fonts); the middle-dot in the
label rendered as garbage on saved screenshots. screenshot_label builds
an ASCII-only 'ID STATE' string for the annotation; the Qt live-view
label is unchanged. 72 tests pass.
