Fix Arc Reactor restart: use bash for source, add systemd service, fix deploy

The admin panel restart command used shell_exec which runs /bin/sh (dash on
Ubuntu) — dash doesn't support 'source', so the venv never activated and the
reactor silently never started.

- admin/index.php: wrap restart in bash -c so 'source' works; try systemctl
  first then fall back to nohup
- deploy/jarvis-arc.service: add proper systemd unit so reactor auto-starts
  on boot and auto-restarts on crash
- deploy/jarvis-deploy.sh: install+enable service file when it changes; mkdir
  log dir before restart; fall back to nohup if systemctl not set up yet
