Fixes the write path, found by exercising it against a real block device.

  • authopen -o flags does not combine with -w: the number was parsed as a second filename and the open failed.
  • The -w form, which copies stdin, kills the process with SIGPIPE if authopen exits early — a crash with no message in a GUI app. Bootsmith now receives the descriptor over SCM_RIGHTS and writes to it directly: no extra copy, no fatal signal, and one authorization covers both the write and the verification.
  • The raw node requires 512-byte alignment. An image whose size is not a multiple of 512 would fail on its final block; it is now zero-padded, and verification reads aligned and trims the excess before hashing.

Tested against a real device: an odd-sized image writes and verifies, and a corrupted sector is detected.
