…re prompting for TPM DUK passphrase Added function show_totp_until_esc() in etc/functions: - Shows "[TIMESTAMP] | TOTP code: XXXXXX | Press Esc to continue..." (pipe-separated). - Caches TOTP for 1 second and only redraws when the second changes (avoids flicker). - Polls input every 200 ms and returns immediately on ESC, printing a blank line for separation. - Shows "TOTP unavailable" when a code cannot be fetched (initial or failure).
