Refactor subscription renewal process to utilize panel webhook

- Removed the recurring billing task from the bot, shifting the auto-renew functionality to the panel webhook service, which now triggers renewals 24 hours before expiry.
- Updated service dependencies to wire the subscription service with the panel webhook for seamless renewal handling.
- Adjusted the Subscription model to enable auto-renew by default, enhancing subscription management.
