fix(oauth): persist rotated Microsoft refresh tokens

Microsoft Entra rotates refresh tokens on every refresh and expects clients to replace the stored token with the new one. The Microsoft provider config was missing supportsRefreshTokenRotation, so the rotated refresh_token returned by Azure AD was silently discarded and the original token from initial OAuth connect was reused indefinitely — causing periodic 'Failed to refresh access token' errors for Excel, Teams, Outlook, OneDrive, SharePoint, Planner, AD, and Dataverse integrations.
