Subject: [PATCH] fix(cli): prevent update crash in non-TTY environments
 (#3094)

cmd_update calls input() unconditionally during config migration.
In headless environments (Telegram gateway, systemd), there's no TTY,
so input() throws EOFError and the update crashes.

Guard with sys.stdin.isatty(), default to skipping the migration
prompt when non-interactive.

Salvaged from PR #2850 by devorun. Closes #2848.
