#839 Add ResponseInterceptor for consistent API response envelope

[vic-Gray]

Area: architecture · Effort: S\n\nWhat: Create a NestJS interceptor that wraps all responses in a { data, meta } envelope.\n\nWhy: Inconsistent response shapes require frontend to handle each endpoint differently.\n\nHints:\n- Implement NestInterceptor and register globally in `main.ts

I’d love to take this on because standardized API responses make frontend integration dramatically simpler and eliminate a lot of repetitive endpoint-specific parsing logic.

I’ll implement a global NestJS interceptor that wraps all successful responses in a consistent { data, meta } envelope, ensuring every endpoint returns a predictable structure regardless of controller or module.

The interceptor will implement NestInterceptor, preserve existing payloads inside data, and populate meta with useful request context where appropriate (such as timestamps, pagination metadata, or request identifiers if already available in the app architecture).

I’ll register the interceptor globally in main.ts so the behavior is applied consistently across the entire API without requiring controller-level duplication.

I’ll also ensure the implementation is lightweight, backward-aware where possible, and covered by tests validating response transformation behavior for both simple and structured endpoint responses.

Hey! I'd like to take on this issue. Plan:

• Implement a NestInterceptor that wraps all responses in { data, meta } envelope
• Register it globally in main.ts

Can I get this assigned?
