🎯 Goal

Add support for downloading file attachments

📝 Summary

• Adds a new Utils.messageListConfig.downloadFileAttachmentsEnabled
• Adds the download and share button to both the FileAttachmentView and the File List view

🛠 Implementation

The design follows the same as the uploading one to keep it consistent. Although it is not the same as the UIKit and Figma. But if a customer wants those designs, we can later provide an alternative.

🧪 Manual Testing Notes

1. Upload a PDF File or any file
2. Wait for the upload to finish
3. Tap on the Download icon
4. Wait for the download to finish
5. A "share icon" should appear
6. Tapping the share icon should open the Share sheet
7. Do the same for the File List (Tap on the top right corner of the Channel > Files)
