- SettingsModal: widen to sm:max-w-3xl with max-h-[90vh] scroll and a
two-column grid so it no longer overflows the viewport. Left column =
status/service checks + canvas prefs; right column groups all auto-sync
config (Zigbee, Z-Wave, Proxmox).
- .env.example: drop ZIGBEE_/ZWAVE_ SYNC_ENABLED + SYNC_INTERVAL — the
auto-sync activation is configured in the Settings modal (persisted to
scan_config.json), same as Proxmox; connection config stays env-only.
