[Canvas Mobile] add a "Collapse All" button within Modules

Problem statement:

Within the Canvas Teacher app and Canvas app, there is no “Collapse All” button in the Modules view as there is in the web version. Without this option, users must scroll through each module individually, which can be time-consuming and difficult to navigate, especially in courses with many modules.

Proposed solution:

Add a “Collapse All” button to the Modules view in the Canvas mobile apps. This feature would improve efficiency and navigation for both teachers and students, allowing users to quickly condense or expand modules and easily locate specific content without excessive scrolling.

User role(s):

admin,instructor
