fix(napplets): expand the "what it can access" section straight down, not from the left

The disclosure used AnimatedVisibility's default transition and the inner servers
Column didn't fill width, so the section faded/expanded while the server list also
grew in horizontally from the left — an inconsistent, weird effect. Make the
transition explicit (fade + expandVertically/shrinkVertically anchored at Top, so
it opens/closes straight down like the card) and fill width on the servers column
so nothing slides in sideways.
