[bug\_fix] The SSO session has expired or is invalid \(aws sso\)

Execute \`aws sso login\` to refresh the OIDC tokens. Unlike long-lived IAM credentials, AWS SSO issues access tokens \(8-12 hour lifetime\) and refresh tokens that eventually expire. The fix re-establishes the browser-based OIDC flow with the identity provider, obtaining fresh tokens stored in \`~/.aws/sso/cache/\`.

Journey Context:
Developer is running Terraform apply using AWS SSO profiles. It fails with 'Error: error configuring Terraform AWS Provider: failed to get shared config profile, SSO session has expired'. They check \`~/.aws/credentials\` and find it empty, then check \`~/.aws/config\` confirming the SSO start URL and region are correct. They try \`aws sts get-caller-identity --profile my-sso\` and get 'The SSO session has expired or is invalid'. Initially they think they need new IAM access keys and navigate to the AWS Console, but realize SSO doesn't use long-term keys. They search the error and find references to \`aws sso login\`. After running it, a browser opens, they authenticate, and the CLI stores new tokens. The subsequent Terraform run succeeds because the AWS SDK now finds valid OIDC tokens to exchange for temporary IAM credentials.
