This pull request introduces the ability to send multiple files in a single message within the Rocket.Chat application. Key changes include:

• File Upload Enhancements: The file upload functionality has been significantly refactored to support multiple files, including updates to the UploadsAPI interface with new methods for managing uploads and handling encrypted content. The Upload type definition now includes both file and URL properties.

• New Components and Hooks: Several new components and hooks have been added to manage file uploads, such as MessageComposerFile, MessageComposerFileArea, and MessageComposerFileLoader, which provide UI elements for file management, preview, and error handling. The useFileUploadDropTarget hook has been introduced to streamline file upload handling.

• Thread and Message Integration: The PR adds support for thread-specific uploads and integrates file upload capabilities into various components like MessageBox, AudioMessageRecorder, and VideoMessageRecorder. The confirmFiles function is introduced to handle file confirmation and sending, with error handling and cleanup processes.

• Localization and API Updates: The English localization file has been updated with new messages related to upload failures and file count limitations. A new API endpoint for media editing has been added to the REST typings.

Overall, this pull request enhances the file upload experience by allowing multiple files to be sent in a single message, improving the user interface, and refining the underlying upload logic.
