Refactor session_list to return session references separately

[stevevanhooser]

Summary

Modified the session_list() method to return session references as a separate list alongside the session details, improving API usability and enabling more efficient access to session reference strings.

Key Changes

• Changed return type from list[dict[str, Any]] to tuple[list[str], list[dict[str, Any]]]
• Extracted session reference strings into a dedicated list returned as the first element of the tuple
• Refactored internal logic to build both session_references and session_list during iteration
• Updated docstring to document the new tuple return format with clear descriptions of each component

Implementation Details

• Session references are now extracted once during iteration and stored in a separate list for efficient access
• The session reference value is reused in the session dict to avoid redundant property lookups
• The method maintains backward compatibility in terms of data content while changing the return structure
