fix: ensure full-height layout

[wgu-jesse-stewart]

Fixes #1695
Related PR: openedx/frontend-lib-special-exams#164
Summary:
When content within a sequence is shorter than the height of the browser viewport, the .sequence-container > .outline-sidebar-wrapper element does not expand appropriately. This causes the course outline sidebar to be partially or completely hidden from view.

Steps to Reproduce:

Open a course sequence that contains very little content (e.g., a short paragraph or notice).

View the course in a tall browser window.

Observe that the sidebar navigation is cut off or hidden.

Expected Behavior:

The sidebar should remain fully visible and accessible, regardless of the amount of content in the main pane.

Actual Behavior:
When the content is short, the parent container height collapses to fit that content, which in turn restricts the sidebar’s height, hiding part of the navigation.

Screenshots:

Removing unnecessary wrapper divs and adding some very specific CSS to target the layout parent.

Comments suppressed due to low confidence (2)

src/courseware/course/sidebar/sidebars/course-outline/CourseOutlineTray.scss:3

• Removing the 'overflow: auto' property may lead to issues if the sidebar content exceeds the available space, causing potential overflow. Consider verifying that this change does not negatively impact the usability of longer navigation lists or apply a conditional overflow handling.

-    overflow: auto;

src/courseware/course/sequence/Sequence.jsx:233

• Moving the CourseLicense component outside of the flex container may affect the intended alignment and spacing within the sequence layout. Please confirm that this change meets the layout requirements across different content scenarios.

        <CourseLicense license={license || undefined} />
