The list is asked with the plan's key, bare in Authorization, at the host its
term (subscription/list) is asked at, so open.bigmodel.cn and api.z.ai alike;
a ZCode account on the built-in gets the same. The tooltip says "The plan's
resets" for a person's own, "The team plan's" for a team's (ResetCredits.Team).
Tested: the reporter's literal reply (ids and times filled in, same shape)
in TestZhipuPersonalResets, TestPlanQuotas and TestZCodeAccounts, each
failing with the change reverted; reset-each-title in Chromium and WebKit,
en/zh/ja/de; a real Z.ai key through zhipuPersonalResets (1 five-hour,
1 weekly). Not tried: a real bigmodel.cn key.
