feat(update-apps): add var_continue_on_error and TERM=dumb fix

Browse Source 
- Add var_continue_on_error=yes to skip failed containers instead
  of aborting all remaining updates. Useful for cron/unattended runs
  where one disabled or broken script should not stop others.
  Containers with backup still attempt restore on failure regardless.

- Set TERM=dumb when running pct exec to prevent whiptail from
  hanging when no TTY is available (e.g. cron jobs redirecting
  stdout/stderr). This causes whiptail to fail-fast instead of
  blocking indefinitely.

- Add var_continue_on_error to export_config_json, --help output,
  and usage examples (cron-style invocation example added).
