One widget, nine buttons (two scenes, lights on/off, two plugs on/off, status). Each press
posts a one-line command to the house bot's private HTTP door and prints the bot's reply --
the devices' read-back -- verbatim. Two allow-lists (lib/Buttons.php here, the bot's own)
must both pass. No build step: plain PHP + one JS file, the speedtest pattern; the widget
registration is integration_gotosocial's, without Vue.
