fix(work-order-dashboard): rename route param to {wo} to bypass model binding

Root cause of the "Fișa #0" bug: the page had
    public ?WorkOrder \$record = null;
and the route slug was work-orders/{record}/dashboard. Livewire/Laravel
saw the {record} param and the typed \$record property with the same
name and attempted route model binding via BelongsToTenant scope. When
that resolution didn't return a Model instance in a Livewire hydration
context, mount() ended up being called with 0, so the button worked
but the destination page redirected saying "Fișa #0".

Fix: rename the route parameter to {wo} so it no longer collides with
the property name, receive it as int|string in mount(), and do the
find() ourselves. The property stays as \$record for the Blade view
but is now always populated by our own code.
