The status popover and select-server dialog used to call navigate('/') then
defer server.setActive to the next microtask. With multiple sidecars in v2,
that split triggered two separate disposal cascades - one for the route
change and a second for the ServerKey Show re-key - and the sidebar project
bucket also swaps (local -> wsl:Debian), tearing down every solid-dnd
sortable in the middle. Wrapping both calls in batch() lands them in a
single Solid update so disposal runs once.
Also raise Error.stackTraceLimit to 200 so future disposal crashes capture
the originating frame instead of truncating at the tenth cleanNode.
