Log Message:
SyncTERM: move transfer-window UI to Wren

Replace the C-side draw_transfer_window/transfer_complete plumbing
and the per-protocol cprintf progress callbacks with a Wren
TransferApp driven by a worker thread + bounded mailbox. C side
runs each protocol on its own thread and pushes pre-formatted
status lines through xfer_tick_lock/get/unlock; the main thread
stays in TransferApp's modal loop, which composes ProgressBar and
LogView widgets.

Worker-to-main marshalling covers the two thread-unsafe UI paths: duplicate-file resolution and the YMODEM->XMODEM filename prompt
fallback. All six protocol entry points (zmodem recv/send/batch,
xmodem/ymodem recv/send/batch, cet recv) now flip binary mode and
hand off to wren_run_transfer; lputs auto-routes via the mailbox
when xfer_session_active().

Drops ~1100 lines of C — the legacy log_ti/progress_ti/transw_ti
windows, ask_overwrite, the per-protocol progress functions, and
the cputs-into-window logging path.
