[bug\_fix] Token has expired and there is no refresh token

Re-run \`aws sso login\` to refresh the OIDC token pair, or configure an \`sso\_session\` in ~/.aws/config to enable the SDK to auto-refresh via the AWS SSO OIDC token endpoint before the 8-hour credential expiration.

Journey Context:
A developer is running a long-lived Terraform apply session that was initialized via \`aws sso login\` earlier that morning. The AWS SSO permission set grants access via temporary STS credentials cached in \`~/.aws/sso/cache/\`. After 8 hours \(the default maximum session duration for AWS SSO\), the temporary credentials expire. The Terraform AWS provider attempts to refresh credentials using the cached OIDC refresh token, but the refresh token itself was invalidated due to the organization's conditional access policy requiring re-authentication every 8 hours. The developer sees 'Token has expired and there is no refresh token' in the SDK logs. The fix works because \`aws sso login\` initiates a new device authorization grant flow against the AWS SSO OIDC endpoint, obtaining a fresh access token and refresh token pair. This allows the CLI to request new STS credentials. Configuring \`sso\_session\` enables the SDK to proactively call the OIDC refresh endpoint before the 8-hour mark, preventing the hard expiration.
