Fix copy-paste duplication bugs in ts/roi.ts

Purpose: Fix compilation errors originating from syntax and scoping issues.
        The previous commit inadvertently introduced severe copy-paste duplicate blocks in several locations:
        - Around the `const runs_per_base = ...` loop inside `render()`, creating duplicate `capexCell`, `profitCell`, and `marketCell` let/const definitions, crashing TS scope logic.
        - Redundant `let savedBuilding` assignments.
        - A malformed partial duplication of `function formatMatPrices() { ... }` that lacked a closing bracket.
        - Redundant object key fields for interface declarations `Metrics`, `Profit`, and `MatPrice`.
        All unneeded redundancies have been surgically cleared, allowing `bun build` to compile properly again.
