refactor: Make blocklist update asynchronous

The blocklist update process is now executed asynchronously.

This prevents the API handler from blocking while waiting for the
update to complete. The response status is changed from `200 OK`
to `202 Accepted` to signify that the reload was triggered but
is running in the background.
