Description

This PR introduces several performance enhancements and user interface improvements. The loading indicator for the map has been updated to include a status message, providing users with feedback during the loading process. In the data export functionality, the payload now excludes large binary fields from photos to prevent errors with large datasets, improving the efficiency of data handling. Additionally, the photo processing logic has been moved to a dedicated web worker, which enhances performance by offloading heavy processing tasks from the main thread. Lastly, the pin icon generation for map clusters has been optimized to process in batches, reducing UI blocking and improving responsiveness during map interactions.
