-- Capture the client app version (the build a report was sent from) with each feedback
-- message, so the operator console can show which version a player was on. Nullable, so the
-- rows that predate this keep working — additive and backward-compatible, so a backend image
-- rollback stays DB-safe (older code simply ignores the column).
