Enhance diary member activity management by adding validation and logging in addMembersToActivity function. Implement checks for participantIds to ensure they are an array, and log relevant information for better debugging. Update DiaryDateActivityService to improve error handling and logging for group activity associations. Modify frontend DiaryView to support group activity member assignment, including new methods for toggling and assigning members to group activities, enhancing user experience and functionality.
