fix(ui): show the FIPS/Tor transport pill on mobile peer files

The peer-files header title block is `hidden md:block` (the global header
carries the peer name on mobile), which also hid the transport pill nested
inside it — so mobile users browsing a peer's files had no indication of
whether they were on FIPS or Tor.

Render a `md:hidden` pill alongside the peer icon so the transport is
visible at every width, without duplicating the peer name on desktop.
