fix(ipam): show VM id/name/IP in IP map tooltip

The IP map tooltip read e.ip, but the backend ip-map endpoint returns
the address as ip_address, so the IP rendered as 'undefined'. Align the
IPAMIPMapEntry type with the backend response and build the tooltip from
proxmox_vmid, resource_name/hostname and ip_address.
