feat: live activity panel with SSE event feed and relative timestamps

Replace static item list refresh with real-time event feed:
- Add _relative_time() helper for human-friendly timestamps
- Prepend SSE events (item updates, new revisions, mode changes) instantly
- Seed feed with 10 recent items on first SSE connect (no per-item revision calls)
- Refresh relative timestamps every 60 seconds
- Cap activity feed at 50 events
- Remove expensive list_items + get_revisions calls on every SSE event
