Enhancements

Clearer error messages for FOTA failures

FOTA error reporting now shows clear messages when updates fail due to the device not being reachable or a message timeout. This makes it easier to understand the reason behind a failed update.

Documentation for group-level widgets

Added user documentation for the feature that allows creating widgets directly at the group level. This improves usability by ensuring users can find guidance on managing visualizations for grouped devices.

Error message for mass device removal

Added a snackbar message when mass device removal fails due to outdated or changed filter settings. This ensures users are now clearly informed about removal errors.

Improved FOTA file upload

Rewritten the FOTA file upload mechanism to use multi-part uploads, enabling better handling of large files. This improves reliability when uploading firmware images and aligns it with the SOTA file upload flow.
