refactor(security): replace HandlerInterceptorAdapter with HandlerInterceptor during upgrade of spring boot 3.0.x

Since `org.springframework.web.servlet.handler.HandlerInterceptorAdapter` has been deprecated in springframework 5.3.0 and removed in 6, replacing it with `org.springframework.web.servlet.HandlerInterceptor`.
```
