Remove the noatime. I don’t know why the Calamares developers insist on adding that for the swap partition, but it’s pointless. A swap partition does not contain any filesystem, and therefore also no files. It’s a raw block device. noatime is a filesystem option, and it has no meaning for a swap partition.
That’s for creating a swap file on a btrfs filesystem. The OP has a dedicated swap partition, which is a different thing. A swap partition does not have any filesystem on it.
It does support swap files, but you have to take special precautions, because a swap file on btrfs must not use copy-on-write or compression. And a dedicated swap partition is still better, regardless of what anyone says.
It will use swap when it needs more virtual memory than your RAM can provide for. But a freshly booted system isn’t going to be swapping just yet. Leave your system on overnight for a couple of days, and you will see that it has begun swapping.
