chore(haproxy-status): regenerate Director basket for URL-embedded basic auth

Drops the now-removed `--username` and `--password` arguments,
their `haproxy_status_username` / `haproxy_status_password`
DataFields and the matching default in the service template.
Notes field re-rendered from the updated DESCRIPTION which now
documents the URL-embedded basic auth pattern.

Existing Icinga services still need to migrate the URL field to
embed the credentials (e.g.
`https://stats:s3cret@webserver:8443/server-status`); the plugin
hard-UNKNOWNs with a clear migration pointer if `--username` or
`--password` are still passed through.
