Fix USB/RAM status checks; add server model+S/N to dashboard; remove cycles

USB Export Drive:
  lsblk reports TRAN only for whole disks, not partitions (/dev/sdc1).
  Strip trailing partition digits to get parent disk before transport check.

LiveCD in RAM:
  When RunInstallToRAM copies squashfs to /dev/shm/bee-live/ but bind-mount
  of /run/live/medium fails (CD-ROM boots), /run/live/medium still shows the
  CD-ROM fstype. Add fallback: if /dev/shm/bee-live/*.squashfs exists, the
  data is in RAM — report status OK.

Dashboard Hardware Summary:
  Show server Manufacturer + ProductName as heading and S/N as subline above
  the component table, sourced from hw.Board (dmidecode system-type data).

Validate:
  Remove Cycles input — always run once. cycles=1 hardcoded in runAllSAT().
