[bug\_fix] AADSTS700082: The refresh token has expired due to inactivity when using Azure CLI

Run \`az login\` to re-authenticate interactively. For service principals, ensure the credential secret or certificate is still valid and re-run \`az login --service-principal\`. Root cause: Azure AD refresh tokens have a configurable but finite lifetime \(default 90 days of inactivity for public clients\). When the refresh token expires, the client cannot obtain a new access token without re-authentication, as the token chain is broken.

Journey Context:
Developer runs a script using \`az cli\` to list resources that worked fine last month. It fails with 'AADSTS700082'. The developer runs \`az account show\` which surprisingly returns the subscription info, assuming they are logged in. They try running \`az account get-access-token\` which fails with the same AADSTS error. The developer checks \`~/.azure/accessTokens.json\` \(or the MSAL cache in newer versions\) and sees tokens with expiry dates in the past. They realize that while the 'account' is remembered in the Azure CLI config, the refresh token \(which was issued 91 days ago\) is now invalid due to inactivity. The \`az login\` command initiates a new OAuth2 authorization code flow, forcing the user to authenticate again and obtain a new refresh token and access token, which are stored in the MSAL cache, restoring access.
