Add a small grid to Projections (and optionally per-quote in Quotes): payback years from calculateAdjustedPaybackYears across escalation {0,3,5,8}% × degradation {1,2,3}%, current selection highlighted. Pure re-invocation of the existing pure function with the already-computed annual savings — no engine changes. Format with the existing formatPaybackYears.

Rationale: every headline number is a point estimate driven by soft inputs the engines are already parameterized by. A grid costs milliseconds and shows whether "7.2 years" is robust or knife-edge.

Acceptance criteria

Grid renders on Projections with current scenario highlighted
Values match single-scenario output for the matching cell
No measurable calculation-time regression

Relations: relates to #11

Add a small grid to Projections (and optionally per-quote in Quotes): payback years from `calculateAdjustedPaybackYears` across escalation {0,3,5,8}% × degradation {1,2,3}%, current selection highlighted. Pure re-invocation of the existing pure function with the already-computed annual savings — no engine changes. Format with the existing `formatPaybackYears`. Rationale: every headline number is a point estimate driven by soft inputs the engines are already parameterized by. A grid costs milliseconds and shows whether "7.2 years" is robust or knife-edge. **Acceptance criteria** - [ ] Grid renders on Projections with current scenario highlighted - [ ] Values match single-scenario output for the matching cell - [ ] No measurable calculation-time regression **Relations:** relates to #11 *(Audit finding F-29, 2026-07-16 — feature, ranked #4)*
