fix: x-data wsInit() was never called — used inline x-data without init

The template had x-data="{inline object}" with x-init="init()" but the
inline object had no init method. wsInit() function was defined but
never referenced. Changed x-data to wsInit() which returns the full
component with init() — Alpine auto-calls init() on mount.
