feat: enhanced timeline hover tooltip with role, dates, status

The tooltip shown when hovering over project strips in the timeline
now includes additional information:
- Role name (e.g. "3D Artist", "Project Manager")
- Assignment date range (2026-03-01 → 2026-06-30)
- Status badge when not CONFIRMED (shows PROPOSED, DRAFT, etc.)
- Lead person and order type on the same line

Data comes from already-loaded timeline entries — no extra API calls.
Safe change: tooltip is pointer-events-none and read-only.
