The bulk-delete trash icon in the Select All row sat off-axis from the
``⋮`` MoreMenu icons of the session rows below: lower (the wrapper had
``py-1 mb-1`` while session rows are ``h-8`` with no vertical padding)
and further left (the trash button was ``p-0`` inside an unpadded
column while the SessionMoreMenu trigger is ``h-8 w-8 p-2``).
Mirror the SessionSelector row shape exactly:
- Outer wrapper: ``flex h-8 items-center justify-between`` — no extra
vertical padding, no bottom margin.
- Trash button: ``size="icon" h-8 w-8 p-2 rounded`` — matches the
SessionMoreMenu trigger inner padding so the icon centers in the
same 32×32 column as ``⋮`` below.
- Inner padding moved to the Select All checkbox cluster (``px-2``)
so the left edge still lines up with the SessionSelector internal
padding.
Drive-bys (touched lines biome would flag otherwise):
- Remove unused ``isDefaultSession`` local in the sessions map.
- Sort the alertStore/flowStore imports.
- Convert the Select All click target from ``<div onClick>`` to a
real ``<button type="button" aria-pressed>`` so keyboard users can
toggle it and the a11y lint warning no longer fires.
Adds ``__tests__/chat-sidebar.test.tsx`` covering: button hidden when
nothing selected, ``h-8 w-8 p-2`` button shape, host row uses ``h-8``
with no ``py-*`` / ``mb-*`` padding, and bulk delete fires with the
expected (default-session-excluded) selection.
