Show only the bundle's name in the sensor configuration row

The row carried the origin, the calibration selection and the SDK's verdict, which a 30 px
line cannot explain; it is now the descriptor's display_name, else the folder name, and the
sensor dialog states the rest under the selector — name and folder, profile, shape, root,
verdict, calibration and every finding — with a suffix only where two rows would otherwise
read alike. Verified with the studio suite, the catalog tests in shared/tests, ui_check and
the lint gate.

+A configuration row in the sensor dialog is **the bundle's name and nothing else**: the
+descriptor's `display_name` when there is one, otherwise the folder name (`box`, `mini`, `finger`,
+`finger-mems`, and whatever the operator called their own folder). Everything else — the origin,
+the resolved root, the `profile_id`, the bundle shape, the SDK's verdict with what it means, the
+calibration selection and every finding — is written in the details surface directly under the
+selector, where the sentences fit.
+
+One exception: two entries offered together that would otherwise read alike each get a suffix.
+Across roots that is the origin (`Box (shipped)` beside `Box (user)`); when one root supplies both
+(for example one `display_name` declared by two folders) the origin cannot separate them and the
+folder is used instead. Nothing is collapsed or shadowed, and the same tree always produces the
+same rows.
