• Refactor group controller with better cache integration
• Add more robust error handling and logging

fix(group): optimize group cache implementation

This commit refactors the GroupCacheRedis implementation to improve code organization and maintainability. The changes include:

• Added proper import organization and removed unused imports
• Implemented batchGetCache2 function calls for efficient data retrieval
• Added comprehensive cache key management functions
• Improved version tracking for group members and requests
• Enhanced error handling and logging
• Added batch operations for better performance
• Refactored complex functions into smaller, more manageable pieces

The changes focus on improving the overall structure and performance of the group cache system while maintaining backward compatibility.

refactor(group): improve notification error handling and add admin context

• Convert notification methods to return errors for better error propagation
• Add admin context checking for bulk notifications
• Enhance group info retrieval with proper error handling
• Improve notification sender with fallback user information

fix(group): handle nil group member map in notification

Add nil check for groupMemberMap[groupInfo.GroupID] before accessing to prevent nil pointer panic. Skip iteration if map is nil.

refactor(group): update group notification methods to use UserInfo struct

Renamed function parameter from groupMemberUserID string to changedUserInfo *sdkws.UserInfo Updated function logic to use changedUserInfo.UserID instead of separate parameter Refactored notification methods to use consistent UserInfo struct pattern Added proper error handling for opUser retrieval
Updated function signatures and internal logic for GroupMemberInfoSetNotificationBulk

fix: batchGetGroupRoleLevelMemberIDs with BatchCache

fix: GetGroupMemberNums BatchCache
