feat: allow script to work with both test and live Stripe keys

- Accept both sk_test_ and sk_live_ API keys
- Show mode indicator (TEST/LIVE) in output
- Adjust webhook URL based on mode (localhost for test, towerops.net for live)
- Add warning when using test mode
- Useful for testing billing setup before going live
