feat(topup): add admin-only audit info to top-up logs

Thread caller IP from webhook/admin controllers through model recharge
functions and record a new RecordTopupLog entry with admin_info (server
IP, caller IP, order payment method, callback payment method, system
version). Frontend shows these fields in the expanded log row and the
IP column for admins on top-up logs, while non-admins continue to see
admin_info stripped by formatUserLogs.
