Refactor session logout logic into helper method

Extracted duplicated session logout code into a new private method, LogoutCurrentSession. This method is now used in both GetWMSessionAsUser and GetWMSession to improve code reuse and maintainability. Exception handling for session logout remains silent to avoid issues with already-terminated sessions.
