Daniel Maksymilian Syrnicki 51cdf460d9 fix: wire webinstaller to archinstall 4.x config schema
Walking-skeleton install on a real VM surfaced two archinstall 4.x
schema breakages that the wizard hit only at runtime:

- `use_entire_disk` was removed as a `config_type`. Now builds a full
  `default_layout` disk_config by calling `suggest_single_disk_layout`
  (forced ext4 + no separate /home, which bypasses its interactive
  prompts) and serializing the returned DeviceModification.
- Credentials keys renamed to plaintext sentinels: `!root-password`
  and `!password`. Users with neither `!password` nor `enc_password`
  are silently dropped by `User.parse_arguments` — which is why the
  first real install booted but wouldn't log in.

Also rolls in Robert's UX feedback quick-wins: `(Recommended)` prefix
on the default boot entry across GRUB/syslinux/systemd-boot, and
less-jargon hints on the step-1 hostname/username fields. iso/README
loses three stale bullets that described pre-15b876c behaviour.
