Implement last participations endpoint and enhance member activity retrieval

Added a new endpoint to fetch the last participations of a member, including group assignment checks for activities. Updated the member activity controller to include logic for filtering activities based on participant group IDs. Enhanced the DiaryView component to display activity statistics and last participations in a modal, improving user experience and data accessibility.
