repairGerman gated subject, body_html and body_text on body_html alone, the
same defect Codex found in migration 194: an admin who had translated only
the subject lost it the moment the HTML still matched English, and down()
is a deliberate no-op, so the loss was unrecoverable. Each field is now
judged independently for both the translations row and the legacy _de
columns, matching 194's corrected pattern. Two tests pin the two
directions (translated subject over English body, and the reverse).
