[bug\_fix] AADSTS700082: The refresh token has expired due to inactivity

Transition from interactive user authentication \(\`az login\`\) to Service Principal authentication \(\`az login --service-principal\`\) or Managed Identity \(\`az login --identity\`\) for automation and CI/CD pipelines. If interactive login is required, run \`az login\` again to obtain a new refresh token. For long-term automation, implement Workload Identity Federation to exchange external identity provider tokens for Azure AD tokens without storing long-lived refresh tokens. Root cause: Azure AD refresh tokens for user accounts have a maximum inactive lifetime \(90 days by default\) and cannot be used indefinitely for non-interactive automation.

Journey Context:
Developer sets up a nightly data sync script on an on-premises server using Azure CLI. Runs \`az login\` once, selects subscription, script works. Three months later, the script starts failing with AADSTS700082. Developer checks the script logs and sees the error appears immediately when trying to list storage accounts. Searches the error code and finds Microsoft documentation stating refresh tokens expire after 90 days of inactivity. Realizes that \`az login\` stores a refresh token in ~/.azure/msal\_token\_cache.json \(or similar\) that is tied to their user account and subject to tenant policies. Understands that refresh tokens are not eternal and that Azure AD tracks the last time a refresh token was used to get an access token. Since the script ran unattended, the 90-day window passed without a full interactive login. The fix is to switch to a Service Principal which uses client credentials flow \(no refresh tokens, just client secrets/assertions\) or to use Managed Identity if the VM is in Azure. Developer creates a Service Principal, assigns RBAC roles, updates script to use \`az login --service-principal\`, and the error never returns because client credentials don't have inactivity expiration.
