Persist hooks to PG instead of Redis

Describe the bug Webhooks are being stored in Redis instead of a persistent database (PG). When Redis is restarted, all hooks created are lost, requiring them to be re-registered.

To Reproduce Steps to reproduce the behavior:

1. Configure and register webhooks in core(using the pre or post hook endpoint)
2. Verify webhooks are working correctly
3. Restart the Redis instance
4. Attempt to use or view previously configured webhooks
5. Observe that all webhook configurations have been lost

Expected behavior Webhooks should persist across Redis restarts. They should be stored in a persistent database (PG) so that restarting Redis does not result in data loss.
