- Implemented utility to calculate wagon usage metrics for train schedules. - Created for sending wagons to maintenance with optional notes. - Added unit tests for train builder maintenance functionalities, including formatting train run labels and building maintenance notes. - Developed component for merging train schedules with detailed previews and reasons for merging. - Introduced component for selecting wagons with search functionality and selection limits. - Created for displaying and filtering audit logs, including detailed views of individual log entries. - Added for handling API interactions related to audit logs, including fetching logs and entity types.
