fix(web): give AI spec-suggestion calls a timeout above the AI provider's

request.js's shared axios instance times out every admin call at 10s,
but AI matching settings allow the server to wait up to 600s
(aimatching.maxTimeoutSecs) for a real chat/completions round trip.
For shopee product 49915704844 the size dimension had no deterministic
match and genuinely called the model; the frontend cut the connection
before the server replied, which the browser reports as a generic
network failure ("服务器连接异常") that has nothing to do with the
actual cause. Override the timeout on just these two calls instead of
the shared default, which stays tight for every other (fast) admin
request.
