The Chat-tab session switcher rendered rows in the API's default
order="created" (original start time) while each row displays
last_active — so a session you just messaged in could sit below an
older one, and the list looked unsorted against its own timestamps.
Pass order="recent" from ChatSessionList so the switcher sorts by
latest activity across the compression chain (most-recently-used at
top, ChatGPT-style; long conversations that auto-compressed into a new
continuation id stay on the first page). Adds an optional, defaulted
`order` arg to api.getSessions; the paginated Sessions page keeps the
stable created order.
Add a ChatGPT-style conversation list beside the embedded TUI on the
dashboard Chat tab so users can swap sessions without leaving the page.
- New ChatSessionList component: lists recent sessions for the active
profile (title/preview, last-active, message count, source), a New chat
button, and a refresh control. Best-effort like ChatSidebar.
- Selecting a row drives /chat?resume=<id>, which ChatPage already treats
as part of the PTY identity, so the terminal respawns resuming that
conversation. Active row is highlighted; New chat clears resume.
- Wired into ChatPage as a dedicated right-side column (desktop) and into
the existing slide-over panel above model/tools (narrow screens).
- i18n: new sessions.newChat key across all locales.
- Read-only switcher by design — delete/rename/export stay on Sessions.
Docs: web-dashboard.md Chat section documents the switcher.
