[Backend][Tech-debt] ~60 @ts-ignore comments defeat type safety across the backend

[Penielka]

Overview

The backend uses @ts-ignore extensively — backend/src/index.ts alone has ~20 of them (imports of services, middleware, and route modules), with more in routes/assignmentRoutes.ts, routes/smartWalletRoutes.ts, routes/secureCommRoutes.ts, middleware/upload.ts, and elsewhere. Many suppress missing module errors (// @ts-ignore - controller module not yet implemented), which is exactly how dead routes (vrf, cross-protocol-bridge) got past CI. @ts-ignore hides real type errors and makes the type checker a no-op for whole files.

Evidence

• backend/src/index.ts — ~20 @ts-ignore (lines 30–112)
• backend/src/routes/assignmentRoutes.ts — 9 @ts-ignore
• backend/src/routes/smartWalletRoutes.ts — 8 @ts-ignore

Acceptance Criteria

• Replace @ts-ignore with real types; where a module is genuinely missing, create it (not suppress it)
• Add an ESLint rule (@typescript-eslint/ban-ts-comment) that fails CI on new @ts-ignore
• Audit remaining suppressions and document each one

Files to Modify

• backend/src/index.ts
• backend/src/routes/*
• backend/.eslintrc.json

Priority: Medium
