codex_auth.py was moved into contrib/codex/ but still used `.log`/
`.util` relative imports that resolved to the parent bot_bottle
package before the move — update to `...log` / `...util`.
_read_winsize() called sys.stdin.fileno() outside the OSError guard;
pytest's redirected stdin raises UnsupportedOperation (an OSError
subclass) there, breaking test_returns_first_tty_size. Move fileno()
inside the try block so any non-TTY stream is skipped cleanly.
