fix(ui): report capture failures in the Plan Cutting dialog

Capturing plates runs inside the dialog's message loop, where only
argument, operation and not-supported exceptions were caught, so any
other capture failure escaped to the editor. Show every capture
failure in the summary with Apply disabled instead.
