• Category Moderation Groups: Implements the import of group-based moderation settings for categories.
• Group Attributes: Adds import support for public_admission, public_exit, allow_membership_requests, and assignable_level.
• User Attributes: Adds import support for trust_level and primary_group_id.
• User Option: Adds import support for the hide_profile_and_presence user option.
• Multiple Tag Groups per Tag: Updates tag import logic to handle tags belonging to multiple tag groups.
