Undocumented apps: per-device filter and wider device column; presence for Skip USMT

- Source Devices in the undocumented-apps list filters by device name, like
  the software columns; Devices and the action column take less room.
- Drop the one-click documented pick (Documented + Only ticked does it).
- Stage legend underline spans label and number.
- Device details title stays on one line; the name truncates instead.
- Presence sweep also pings devices under Skip USMT tags.
