Subject: [PATCH] fix: raise timeout for trader lifecycle calls to survive slow
 stop/restart
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Live click-through showed PUT /traders/:id taking 33.8s (stopping the running
instance waits for its in-flight cycle and monitor goroutines) while the axios
default timeout is 30s — the frontend aborted a request that succeeded
server-side and reported a false launch failure. Create/update/start now use a
120s ceiling.
