Checklist

General

• I tested all changes and their related features with all corresponding user types.

Client

• I strictly followed the client coding and design guidelines.

Motivation and Context

The "Back" button on the Assessment page was previously located in a sticky footer, which was inconsistent with the navigation pattern in other interview pages (e.g., InterviewDetailOverview). Additionally, the header styling (font size, alignment) differed from the standard page headers

Description

Moved navigation: The "Back" button is now positioned in the top-left corner of the header, next to the title.
standardized styling: Applied the project's standard .page-header and .h1-text classes to ensure the title size and vertical alignment match other pages.

Prerequisites:

5. Verify:
   The Back button is now located in the top-left header area (next to the title).
   The sticky footer at the bottom of the page has been removed.
6. Verify: Clicking the back button correctly navigates back to the previous page.
