Implement hierarchical marking in checkboxes

There is hierchy in the roles defined in the organization. `Viewer -> Editor -> Admin`

Editors have all rights of viewer, and Admin have all rights of Viewer + Editor.

## Problem
right now in the frontend, when a user clicks a checkbox in the **viewer column**, the checkboxes of **editor column** and **admin column** do not automatically get selected. Whereas those permissions are granted by hierarchy.

Start by locating the frontend logic that renders the viewer, editor, and admin checkbox columns and handles checkbox changes. Trace how selecting a viewer permission affects the higher-role columns, then verify that editor and admin are selected according to the stated hierarchy.
