Start the Planner authentication flow. IMPORTANT: Only call this tool when you receive an authentication error (e.g. 'Not authenticated') from another tool, or when the user explicitly requests re-authentication. Do NOT call this proactively before using other Planner tools - they automatically use the stored token. If a valid token already exists, this returns immediately without starting a new auth flow.

Check if the authentication is complete. Only call this after auth_start returned a verification URL and the user has completed sign-in on the Microsoft website. Do NOT call this unless you just ran auth_start and it returned a code/URL for the user to visit.
