Setup wizard: full first-run flow for HOST1 and HOST2

Varaverk.page: also shows wizard when local host.conf is missing
  (handles master.conf pushed by HOST1 before HOST2 installs plugin).

pages/setup.php: three wizard flows
  - Standard: blank master.conf, fill hostnames, redirect to scheduler
  - Host2/state file: state file detected, pull master.conf from HOST1 via SSH
  - Conf-only: master.conf already filled (was pushed), just create local host.conf

api/setup.php:
  - save action: writes master.conf + host.conf, creates varaverk_setup.db state file,
    redirects to ?tab=scheduler&vv_setup=master.conf
  - pull action: resolves HOST1 Tailscale IP, queries HOST1 SCRIPTS_DIR, SCPs
    master.conf, creates local host.conf, redirects to ?tab=scheduler&vv_setup=hostN.conf

include/config.php: vv_setup_state_read/write/push helpers.
  vv_push_setup_state() pushes varaverk_setup.db to /boot/config/ on all known
  remotes — no plugin-readiness probe needed (flash is always accessible).

api/rawconf.php: calls vv_push_setup_state() alongside master.conf push.

pages/scheduler.php: setup mode via ?vv_setup=<conf> URL param.
  Auto-opens the specified conf file on page load (DOMContentLoaded).
  vvSaveRawConf: in setup mode, skips confirm dialog and forces sequence:
    master.conf save → auto-open hostN.conf
    hostN.conf save → redirect to Monitor (setup complete)
