OK so looking at your
zfs list output:
NAME USED AVAIL REFER MOUNTPOINT
attatbiqat/lxd/containers/queue-notification-primary 97.6G 42.1G 5.61G /var/snap/lxd/common/lxd/storage-pools/usetyenziso/containers/queue-notification-primary
You can see its used almost 100GB, and has 42GB left - which aligns with what you see in
df inside the container.
lxc storage volume ls usetyenziso shows it has 1 snapshot volume.
So this likely means that of the 150GB you originally set, the snapshot is consuming 100GB of space - likely because there have been lots of changes inside your container since you took the snapshot.
