Add support for handling file action confirmations during uploads, including the ability to process send confirmations from peers. Enhance the file transfer protocol by introducing a new method to build and handle file metadata digests prior to upload blocks. Update related tests to ensure proper encoding of file response digests for uploads.
Refine the RustDesk file transfer protocol by correcting the FileAction mapping for uploads and downloads, ensuring full remote paths are used. Implement optional zstd block decompression for downloads and improve transfer progress reporting. Update related tests for clarity and accuracy in encoding file transfer requests.
Web remote was encoding Auth2FA under auth2Fa, which protobuf.js drops as an
empty message, so RustDesk peers never received the TOTP code after Verify.
