refactor: simplify LaunchDarkly context and remove redundant code

Extract role and segment logic into reusable _add_role_to_attributes helper function.
This removes the duplicate code between use_user_id_only and full context paths.

- Add _add_role_to_attributes() helper function
- Remove duplicated role/segment logic in is_feature_enabled()
- Cleaner, more maintainable code with single source of truth
