Fix exiftool warning pollution + verify screen messaging

Copier: exiftool output parsed with stderr separate; Warning:/Error:
lines stripped from stdout so IPTC/XMP warnings don't appear as
the Make value.

VerifyScreen:
- 'kept on phone' suffix on unverified only shown when deleteAfterVerify=on
- Summary header adapts: no delete messaging when delete is off,
  '(pre-unchecked)' label only when checkboxes are visible
