Gantt bars use the capacity-aware lane layout (match the forecast)

Browse Source 
ganttView ran schedule() — the single-serial-worker layout — while the Monte
Carlo forecast ran scheduleWithCapacity() over the real lanes. So the bars you
saw didn't match what was forecast (serial 1.0/day vs the team's actual lanes).

Switch ganttView to scheduleWithCapacity(open, deps, workers): startDay/endDay
now come from the same lane layout each forecast trial uses, and `who` shows the
lane an issue actually landed on (falling back to assignee, then blank). The
dogfood harness had the same split — updated it to match and to print the lane
per row.

Verified: typecheck clean, 14 fixture e2e green, live-onboarding e2e renders the
real capacity-aware Gantt with no uncaught errors.
