policy: More defensive code validating svc:DurationSeconds (#19820 )

Set `MINIO_BROWSER_REDIRECT_URL` to `https://console.minio.example.net` to ensure the browser receives a valid reachable URL.

-Similarly, if your TLS certificates do not have the IP SAN for the MinIO server host, the MinIO Console may fail to validate the connection to the server. Use the `MINIO_SERVER_URL` environment variable  and specify the proxy-accessible hostname of the MinIO server to allow the Console to use the MinIO server API using the TLS certificate.
-
-For example: `export MINIO_SERVER_URL="https://minio.example.net"`
