The chat window used to fire two parallel session queries (active subset + full list) and surfaced them through two UI entry points (the title dropdown + a History icon panel). The two caches drifted during the WS-invalidate window — visible as "completed → reload → ghost row" flickers — and the History toggle was a redundant entry into the same underlying data. Collapse to one cache (full list, ?status=all) and one entry point (dropdown). The dropdown groups locally into Active / Archived; the archived group is collapsed by default with a count, and per-row delete moves into the dropdown via hover-revealed trash + confirm dialog. Backend stays untouched: old desktop builds still hit GET /chat-sessions without ?status and continue receiving the active subset, so installed clients are unaffected.
