fix: Invalid CanActivate guard in cmsMapping

[kpawelczak]

closes: CXSPA-7552

This change was made to break the reference to the canActivate array in the routing configuration. The previous implementation directly modified the route.canActivate array, leading to unintended side effects when the function was re-executed, particularly with lazy-loaded modules.

if (route?.canActivate?.length) {
  const canActivate = route.canActivate.map((guard: any) =>
    this.wrapCmsGuard(guard)
  );
  return {
    ...route,
    canActivate,
  };
}

Reason for the Change:
This change was implemented to avoid mutating the original route object, which could lead to issues in the following scenario:

• Lazy-loaded module: The function is triggered each time a lazy-loaded module is loaded.

• Logout and Re-login: After logging out and then logging in again, the routing function is triggered again.

• Side effect: On the second execution (e.g., when navigating to "my-account/my-company"), the canActivate guards were already overwritten due to reference mutation in the previous run.

By breaking the reference and returning a new route object with a copied canActivate array, we make sure that each execution works with a fresh set of guards without mutating the original route object.

note:

• spread operator was not enough to break the reference
• JSON method breaks the object type and would require retyping the route object
