feat: add GET /vouching/requests endpoint for mentors

[EmeditWeb]

Problem

Mentors have no way to see who has requested
a vouch from them. There is no endpoint for
incoming vouch requests.

What To Build

Add GET /api/v1/vouching/requests endpoint.
Requires JWT auth (mentor wallet).

Returns list of learners who have requested
a vouch from the authenticated wallet.

Each item includes:

• learner wallet address
• learner reputation score
• requested loan amount
• loan purpose
• request timestamp

Files To Touch

• src/modules/vouching/vouching.controller.ts
• src/modules/vouching/vouching.service.ts

Acceptance Criteria

• Returns only requests for authenticated wallet
• Includes learner reputation score
• Full Swagger documentation
• npm run build passes

Mandatory Checks Before PR

• npm run build passes
• Swagger decorator added
• PR references this issue

Hello,

I would like to apply for this issue.

I have experience developing backend APIs, implementing authenticated endpoints, and working with RESTful services, database queries, and API documentation. I am comfortable working with JWT-based authentication, controller-service architectures, and ensuring endpoints return properly scoped data for authenticated users.

For this issue, I can implement the GET /api/v1/vouching/requests endpoint to return only vouch requests associated with the authenticated mentor wallet. I will ensure the response includes learner wallet addresses, reputation scores, requested loan amounts, loan purposes, and request timestamps as specified. I will also add comprehensive Swagger documentation and verify that the build passes all required checks.

I focus on clean, maintainable code and API security, and I would be glad to contribute this feature to improve the mentor vouching workflow.

Thank you for your consideration.
