- Move _maybe_set_title() to run at start of respond() generator (before streaming)
so titles are set even if the generator is closed mid-stream by Gradio
- Refresh sidebar conv list on first streaming chunk for immediate title display
- Backfilled 34 existing conversation titles from their first user messages
- Add scheduler loop status cards (heartbeat, poll, clickup, folder_watch) to
both System Health and Notifications tabs in the HTML dashboard
- Loop cards show relative time (e.g. "3m ago") with color-coded status
