+Drop the `Message.blockedReason` field. senderkit-app (#211) confirmed the
+abuse scanner's detailed block reason is operator-only and is never returned
+by the public messages API — customer-facing reads omit the column entirely
+and a `blocked` message exposes only a generic `blocked` entry on its
+`timeline`. The previously-added `blockedReason` field would therefore never
+be populated, so it has been removed and the `Message.status` /
+`MESSAGE_STATUSES` docs updated to match. The `blocked` status itself is
+unchanged.
