Remove dead transaction module

[dotunv]

Description

The transaction/ module is a dead stub that always throws NotFoundException with "implementation pending." All functionality lives in the inspector/ module.

Files:

• apps/api/src/modules/transaction/transaction.service.ts
• apps/api/src/modules/transaction/transaction.controller.ts

Current State

• Module is not registered in app.module.ts (commented out)
• Service only contains a TODO comment
• Controller has no working endpoints
• Superseded by the inspector/ module

Proposed Fix

1. Delete the entire transaction/ directory
2. Remove the commented-out TransactionModule import from app.module.ts
3. Update any references to point to inspector

Acceptance Criteria

• transaction/ directory is removed
• No dead imports remain in app.module.ts
• Application builds and starts without errors

Hi @dotunv, I'd like to work on this. The scope is clear — delete the transaction/ directory, remove the commented-out TransactionModule import from app.module.ts, and verify the app builds cleanly. I'll also grep for any remaining references to TransactionModule or transaction imports across the codebase before submitting. Could you assign this to me?

Hi @dotunv, I'd like to work on this issue.

I have experience with NestJS and TypeScript codebase cleanup. I'll remove the unused transaction/ module, eliminate the commented-out TransactionModule import from app.module.ts, update any remaining references to use the inspector module where needed, and verify the application builds and starts successfully without regressions. I'll submit a clean, focused PR that satisfies all the acceptance criteria.
