/***********************************************************************************************************************************************************************
|
|
* File Name: media.controller.js (admin)
|
|
* Type of Program: Controller
|
|
* Description: Issues short-lived JWT stream tokens for admin asset preview.
|
|
* Works identically to the client media token flow but is scoped to
|
|
* admin-authenticated requests and allows any asset regardless of
|
|
* is_public. The stream endpoint (/api/client/media/stream/:token)
|
|
* is shared — the JWT payload shape is identical.
