- ConnectionConfig: new file_path and delay fields - ConnectionRow: File page with path input, Browse button, delay spinner (0–10 s), and auto-fill of receiver-ID from filename - ReceiverManager.connect_receiver: FileBackend wired for 'file' type; UBX poll timer skipped for file sources - FileBackend.register_xcvr: fallback to first unoccupied entry when name does not match filename pattern Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
