feat(TrainingStats): enhance training statistics view and participant details

- Updated TrainingStatsService to include member details (first name, last name) in participant data. - Modified TrainingDetailsDialog to remove unnecessary time display for training sessions. - Added new filters for training days in TrainingStatsView, allowing users to select specific training days and view attending members. - Enhanced localization files to support new training day filter and participant-related strings across multiple languages.
