feat(web): make the preset card the control that picks it

Four changes to the Agent 预设 section, all from the same reading: choosing
a preset is the common act and everything else is occasional.

Picking is now clicking the card rather than hunting a small "Set as
default" button. The card body is the button; the action row sits outside it
because nesting buttons is invalid and those actions operate ON a card
rather than select it. The body's accessible name is set explicitly —
otherwise it is the whole card read aloud, title through id.

Actions are icon-only with their label on hover and on `aria-label`, so four
controls stop competing with the content for attention.

Built-in and custom presets are separated under headings, and the trust
badge moved up beside the title where it qualifies the name. A group with no
members renders no heading.

`Local` reads as a location; these are the user's own, so the badge and the
heading both say `Custom` / 自定义.
