Fetch per-disk temp and spin state for the Storage card

The GraphQL query only asked for aggregate array fsSize/fsFree, so the
per-disk breakdown added in templates/dashboard.html (commit 5045316)
had no data to render. Now pulls name/device/temp/isSpinning for data
disks, cache disks, and parity disks, and shapes them into the
disks/caches/parities lists the template expects.
