GatewayService: - onScanStopped() now calls scheduleReconnect() when not connected, so if the scale is off at startup the service keeps retrying every 8s instead of giving up after the first 20s scan window SettingsActivity: - Add 'Riconfigura bilancia' button (yellow outline) when a scale is already configured — clears saved device, stops the gateway service, and opens SetupActivity directly at step 4 (scale scan step) SetupActivity: - Accept 'start_step' intent extra to jump directly to a specific step (used by SettingsActivity reconfigure flow)
