Fix editor sheets: wrong title on edit, missing padding

Both Snippet and Replacement editors used @State to check if the
entry name/trigger was empty to decide the title. Since @State
captures the initial value, editing an existing entry could still
show "Add" if SwiftUI reused the view. Pass an explicit isEditing
flag instead.

Also move padding inside the editor body and remove the conflicting
outer .padding(20) on the sheet content.
