Documents the two opt-in SAML settings added in NudgeBee: SAML_FORCE_AUTHN (the IdP asks for credentials on every sign-in) and SAML_LOGOUT_URL (logging out of NudgeBee also ends the IdP session).

On the SAML page:

• both variables in the optional table;
• a section for each, with AD FS and Okta setup for Single Logout, including the warning that it signs users out of other apps behind the IdP;
• the new /api/auth/saml/logout and /api/auth/saml/slo endpoints, and the metadata note;
• the singleLogout / config.forceAuthn health fields;
• troubleshooting rows for "signed straight back in after logout or an idle timeout".

npm run build passes.

Code Review

This pull request updates the SAML integration documentation to introduce two new configuration options: forcing authentication on every sign-in (SAML_FORCE_AUTHN) and enabling Single Logout (SAML_LOGOUT_URL). It provides comprehensive setup instructions for AD FS and Okta, details the updated health check endpoint responses, and adds troubleshooting guidelines. The review feedback suggests correcting British English spelling ('honours') to US English ('honors') to ensure consistency across the documentation.
