feat: dynamic /ks-auto kickstart for ISO boot (R1 ARM support)

Add state-aware kickstart dispatch for machines that boot from ISO
(no PXE/network at UEFI level). Replaces hardcoded discover.ks.

- /ks-auto: %pre detects MAC, queries /api/machine-state/<mac>,
  writes discover or install kickstart to /tmp/dynamic.ks,
  main body %include's it
- /api/machine-state/<mac>: simple state endpoint returning
  unknown|discovered|queued|installing|installed|debug
- ISO kernel cmdline updated: discover.ks → ks-auto
- Handles: discovery (first boot), install (queued), debug modes
