Display IP address for customer creation

🔍 Problem Statement
As an admin managing fraud prevention, I experience Pelcro only showing the IP address of the last login — not the original registration IP — which limits my ability to identify and block fraudulent account creation patterns.

💡 User Story
As an admin, I want to see the IP address used at account creation alongside the last login IP, so that I can identify fraud patterns and take action on suspicious registrations.

🎯 Definition of Done
- Given a customer record, when viewed in the dashboard, then the creation IP address is displayed alongside the last login IP.
- This change impacts the UI (customer detail view) and API (customer record — store and expose createdFromIp).
- Limitations: creation IP cannot be backfilled for existing accounts.

On the customers view, the Pelcro platform UI currently displays the IP address for the last customer login event. If a user registers, but never actually logs in, no IP address is displayed. It would be very useful if Pelcro would also display the IP address from which a customer was created. This would be very helpful in battling fraudulent signups where we may want to block ranges of IP address on our site.
