fix(web): name the preset in General settings, and say 预设 in Chinese

The preference row rendered `option.id` while every other surface — the
new-session chip, the session header label, the preset cards — renders the
metadata name. So the same roster read `标准模式` on one screen and `standard`
on the next, and the id is addressing, not a label. A preset that names itself
nothing still falls back to its id, which is then all there is to say about it.

The row's Chinese copy also still ended on the English word: the section is
`Agent 预设`, so the sentence about a running session keeping its composition
says 预设 too.
