/***********************************************************************************************************************************************************************
|
|
* File Name: task_upload.controller.js (client)
|
|
* Type of Program: Controller
|
|
* Description: Handles file uploads for task completion attachments.
|
|
* Files are uploaded to S3 (Garage) via s3.service.js.
|
|
* Returns file metadata for use in the completion submit payload.
|
|
*
|
|
* This is intentionally separate from the completion submit endpoint
|
|
* so the client can upload files first, then submit completion with
|
|
* the returned file references — matching the two-step flow in
|
|
* ViewTaskDetails.jsx handleSubmit().
|
|
*
|
|
* Route: POST /client/groups/:groupId/task-lists/:taskListId/tasks/:taskId/upload
