feat(pxe-boot): switch NFS mount to HA cluster LAN VIP
Updates mount-pxe-images.nix to mount pxe-boot/images from
ha-vip-lan.sweet.home (Pacemaker vip-lan, 192.168.2.229) instead of
server.sweet.home. Storage root changes from /tank to haStorageRoot
(/srv/ha-data). NFSv3+nolock options for LXC are unchanged.

Removes nfsServerHost and storageRoot from variables.nix — all NFS
clients now reference the HA cluster directly (docker via haStorageNfsFqdn
on VLAN 20, pxe-boot via ha-vip-lan on VLAN 2). Updates the nfsShares
comment to reflect the new single-source-of-truth role without the
dead server.nix references.

DNS records for server.sweet.home and server.storage.home were already
cleaned up automatically by IPA dynamic DNS when the VM was deleted.
