Get Messages Since

Return messages between two users that arrived AFTER since.

Used by the frontend after a WebSocket reconnect to backfill messages that may have arrived while the socket was offline. Without this, a user who briefly loses connection sees no messages until they reload — inbox and open thread both appear frozen.

The caller passes the timestamp of the newest message it already has locally. The server returns everything strictly newer, ordered ASC so the client can append directly.
