PaulVua 5777b35770 Add WiFi and HDMI power saving features for remote sensors

Implements power saving optimizations to extend battery life on solar-powered remote air quality sensors:

- WiFi Power Saving: Disable WiFi 10 minutes after boot to save ~100-200mA
  - Configurable via web UI checkbox in admin panel
  - WiFi automatically re-enables after reboot for 10-minute configuration window
  - Systemd timer (nebuleair-wifi-powersave.timer) manages automatic disable
  - New wifi/power_save.py script checks database config and disables WiFi via nmcli

- HDMI Disable: Added hdmi_blanking=2 to boot config to save ~20-30mA
  - Automatically configured during installation

- Database: Added wifi_power_saving boolean config (default: disabled)
  - Uses INSERT OR IGNORE for safe updates to existing installations

- UI: Added checkbox control in admin.html for WiFi power saving
  - Includes helpful description of power savings and behavior

- Services: Updated setup_services.sh and update_firmware.sh to manage new timer

Total power savings: ~120-230mA when WiFi power saving enabled
