Pull request overview

This PR introduces an optional is_full_admin configuration parameter that allows users without full admin privileges to use the okta_user table without encountering permission errors when querying the assigned_roles column.

Key Changes:

• Added is_full_admin configuration field that defaults to false
• Modified listAssignedRolesForUser to conditionally fetch user roles only when is_full_admin is enabled
• Added helper functions for retrieving boolean configuration values with environment variable fallback
