Show discovered devices and shrink bluetooth header buttons

- Scan and Manage are now small icon-only buttons in the header beside
  the On/Off pill, with hover tooltips via the new PillButton.tooltipText
  prop (backed by QtQuick.Controls ToolTip).
- New discoveredDevices list pulls everything in Bluetooth.devices that
  isn't paired/connected/bonded/trusted. While scanning, those appear
  under a 'Discovered' header. Click pairs and connects.
- Empty-state text only shows when there are no known and no
  discovered devices, otherwise it would push down real entries.
