- Add SAML session fields (ProviderID, NameID, SessionIndex) to
SessionData and sessionPersisted structs for persistence
- Add CreateSAMLSession method to store SAML-authenticated sessions
- Add GetSAMLSessionInfo method to retrieve SAML session data
- Update establishSAMLSession to properly store SAML info instead
of delegating to OIDC session creation
- Implement getSAMLSessionInfo to retrieve session info for SLO
This enables proper SAML Single Logout by storing the NameID and
SessionIndex from the SAML assertion, which are required to construct
valid LogoutRequest messages to the IdP.
