mobile UI: rescan button on DC Download page rescans BT/BLE/USB
This way even if a USB device wasn't added through an Android intent, we still have a way to scan for it and select it. This is especially important in case a user has a cable that we haven't seen yet (i.e. with a VID/PID that we haven't added to Subsurface-mobile), but that nevertheless works with the android usb serial drivers. This also makes the flow a little more logical / consistent when deciding which connections to show. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
