"""Regression test for the TUI gateway's ``session.list`` handler.

Reported during the TUI v2 blitz retest: the ``/resume`` modal inside a
TUI session only surfaced ``tui``/``cli`` rows — telegram/discord/whatsapp
sessions stayed hidden even though the user could still paste the id
directly into ``hermes --tui --resume <id>`` and get a working session.

The fix removes the adapter-kind filter so every session the DB surfaces
appears in the picker, sorted by ``started_at`` like before.
