ModelAdapterModal.vue described OpenAI extra params as "合并到" (merge into)
the request body, but the backend (request_override.go:applyExtraParams)
writes body[name] = value — same-name fields are overridden, not merged.
This contradicted ModelEditor.vue's tooltip ("覆盖到...同名字段以这里为准")
and risked users expecting array fields like `tools` to be appended,
which would silently replace the built-in function tools.
Align the modal tooltip with the editor view and the actual override
semantics.
