Subject: [PATCH] test : pin the server mode in the add menu a11y story

The story asserts the add menu's first enabled item is the reasoning submenu, which is mounted only outside router mode. The vitest dev server proxies /props to whichever server is running, so the assertion depended on the machine's server mode and failed whenever a router was up.

Pin the mode in the story, including props.role so a re-detection cannot flip it back.
