The PBS storage plugin used PVE code to detect if an API token was entered in the username field. This lead to bad requests for some valid PBS tokens which are not valid PVE tokens. Examples are "root@pam!1234" and "root@pam!_-". Relax the token pattern to allow token names and realms that start with numbers or underscores. Also allow single character token names, which are allowed on the backend even though they can't be created through the PBS Web UI.
