feat(web-ui): add pinned sessions and live monitor in Chat (#118)

* feat: add single-page live session monitor and chat pinning

* fix: restore full test green after main merge

* fix: use Array.from instead of Set spread for ts-node compatibility

[...new Set()] requires downlevelIteration which isn't enabled in
ts-node dev mode, causing sonic-boom crash on startup.
