feat(cli): add cron subcommand for managing scheduled routines (#1017)

* feat(cli): add cron subcommand for managing scheduled routines
  Rebase onto staging branch and address collaborator review:
  - Fix .unwrap_or(None) → proper error propagation in set_enabled()
  - Add --yes/-y flag for non-interactive deletion with confirmation prompt
  - Add --json flag for machine-readable output in list and history
  - Preserve error context chain with {e:#} in run_cron_cli()

  Note: GATEWAY_USER_ID is trusted from the environment; future work may
  add authentication for multi-tenant deployments.

* fix(cli): reject invalid cron timezones

* refactor(cli): rename cron subcommand to routines

The system manages all routine types (cron, webhook, event, manual),
not just cron schedules. Rename the CLI subcommand to reflect this:
- `ironclaw cron` -> `ironclaw routines` (with `cron` as hidden alias)
- List shows all routines by default, add --trigger filter
- Remove cron-trigger-only validation
- Simplify require_routine helper (no trigger type check)
