Suggest /login command in auth error messages

Problem Statement

My authorization expired in vscode for a remote ssh session and I was unable to get access to the claude plugin
Also could not figure out how to re-authenticate
After much churn on the web interface - it finally suggested I enter /login which immediatly got me working

Proposed Solution

When Claude Code displays an authentication error (e.g. "Your organization has disabled Claude subscription access"), it should suggest running /login as a remediation step. Users switching from personal to corporate accounts may have stale credentials and /login is the quickest fix, but it's not surfaced in the error message.
