fix: unwrap [{data:[...]}] wrapper in server webhook response parsing

The new webhook wraps data in an outer array: [{data: [...]}].
The old parsing only handled {data: [...]} directly, so .data was
undefined and the server list ended up empty — causing the location
to fall through to the slugified default.
