- the header title drops its "UICC" prefix — "GSMTAP trace analyser" is enough
- the trace topbar's search input is half its previous width (flex basis
33.333% -> 16.667%); the session name now ellipsizes instead of wrapping
the tighter row
- the side-panel view selector moved out of the scrollable side panel into
the trace topbar: right-aligned over the panel at the panel's width
(--side-panel-w: 260px, the negative right margin cancelling the topbar's
16px padding so the edges line up), so it stays visible at all times while
the panel scrolls
- tests: the topbar/selector position pins (the Files-view wiring test and
style.test.js), the shared width variable, the halved search basis and the
title; 527 Python + 61 Node tests
