Deleting a session in the desktop app fired instantly on click — the CLI
path (hermes sessions delete) asks y/N by default, so one misclick (Archive
and Delete sit right next to each other) permanently destroyed a conversation
with no dialog and no undo (#61470).
Route every delete entry point (sidebar rows, tab menus, the chat header,
context menus — all share useSessionActions) through a shared
DeleteSessionDialog built on ConfirmDialog. ConfirmDialog gains an
onOpenAutoFocus prop so dialogs with no input keep focus off the close
button (a11y).
Tests: menu delete now asks; cancel keeps the session; Enter confirms;
Escape cancels; delete item disabled without onDelete; the same guard
applies via SessionContextMenu.
