fix(web): make printed cut instructions legible

Keep part numbers and their dividers visible in monochrome print output, and include the selected cutting tool and kerf on the printed report.

 - **Job stock** — Jobs must have stock explicitly configured (catalog-sourced `StockItem` rows or custom-length rows); there is no fallback to auto-discovered inventory
 - **Optimization persistence** — Results saved as JSON in `Job.OptimizationResultJson`; DTO layer (`SavedOptimizationResult` etc.) handles serialization since Core types use encapsulated collections; results auto-cleared when parts, stock, or cutting tool change
 - **Job lock flow** — Optimize job -> review/print results -> Lock Job (manual action beside Print Report on the Results tab, available whether or not purchases are needed) -> job becomes read-only until Unlock
+- **Printed cut badges** — Print styles intentionally remove color fills; cut badges therefore force black text and a black part-number/length divider so both remain legible on paper. The print-only tool line shows the selected cut method and kerf immediately below the summary.
 - **Timestamps** — `CreatedAt` defaults to `GETUTCDATE()`; `UpdatedAt` set on modifications
 - **Collections** — Encapsulated in Core; use `AsReadOnly()`, access via `Add*` methods
 - **Priority system** — Lower priority bins used first in packing algorithm
