Align sized cluster seeds and GET dumps with PVE wire shapes; restyle DATA panel.

- Scale small/large/big seeds (3×50 / 10×1000 / 20×2000) with proportional
  backups, snapshots, HA, replication, Ceph capacity, and OSD totals
  (10 / 100 / 500) plus matching node disks and crush/pg metadata
- Enrich handler responses for apt, certificates, qemu/lxc status, storage,
  SDN, metrics export, and related cluster/node dumps
- Flatten nested body_example fields into PARAMS and sync the request body
  via dotted paths (oVirt-style)
- Restyle DATA controls as size cards with full-width Reset to minimal /
  Refresh stats; unload reloads the minimal cluster
