fix(merge): resolve post-merge type errors from batch-1 agents

- ScenarioPlanner.Baseline.shortCode: string → string | null (matches Prisma)
- ScenarioPlanner.SimulationResult.chargeabilityTarget: number → number | null
- Remove runtime Zod parse from scenario procedures (typed by Prisma already)
- Float64Array index access: add non-null assertions for noUncheckedIndexedAccess
