[bug\_fix] Azure AD AADSTS7000222: Client secret has expired

Navigate to the Azure Portal > Microsoft Entra ID > App registrations > \[Your App\] > Certificates & secrets. Under 'Client secrets', generate a new secret, copy the 'Value' \(which is only shown once\), and update the application's configuration \(environment variable, Azure Key Vault reference, or secrets manager\) to use the new secret. Client secrets in Entra ID have a mandatory expiration period; once passed, the token endpoint rejects authentication attempts.

Journey Context:
A DevOps engineer deploys a new release of a background worker service that uses \`DefaultAzureCredential\` with environment variables for \`AZURE\_CLIENT\_ID\`, \`AZURE\_TENANT\_ID\`, and \`AZURE\_CLIENT\_SECRET\`. The deployment succeeds, but pods immediately enter \`CrashLoopBackOff\`. Logs show \`AuthenticationRequiredError: AADSTS7000222: The provided client secret has expired\`. The engineer remembers creating that secret 24 months ago. They open the Azure Portal, navigate to the App Registration, and see the 'Expired' tag on the old secret. They click 'New client secret', set it to expire in 12 months, copy the value, and update the Kubernetes secret. The pod restarts and successfully acquires an access token for the Key Vault.
