Subject: [PATCH] [feat](trx-frontend-http): show distinct connection loss
 messages in UI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the SSE stream drops (onerror or 15s heartbeat timeout) show
"trx-client connection lost, retrying…". When the stream is live but
server_connected is false, show "trx-server connection lost".
