Replace the BlockDeviceInfo TypedDict and the per-call disk_is_available() check with a dataclass that includes availability as a field, determined once at scan time using mountpoint, mdadm, LVM, and ZFS checks. Extend enumeration to cover mdadm arrays and multipath devices in addition to local disks. Update all callers to use attribute access instead of dict subscript.

zpool destroy removes the pool but leaves ZFS member signatures and the partition table on disk, causing the device to appear in use on the next test run. Signed-off-by: Gaëtan Lehmann <gaetan.lehmann@vates.tech>
Add a WWN field to BlockDeviceInfo (populated from lsblk for local disks, and from the DM alias for mpath devices). In the disks fixture, use WWNs to: - Mark a LUN unavailable on all hosts if it is already in use on any host (cross-host deduplication for shared FC/iSCSI LUNs). - Sort LUNs listed in LVMOHBA_DEVICE_CONFIG or LVMOISCSI_DEVICE_CONFIG to the end of each host's disk list, so they are only selected by other tests when no other disk is available.

Some block devices may be used to build other devices (mdadm, lvm) or be accessible on multiple hosts, but only usable on a single one at a time (fc, iscsi).
