[FEATURE REQUEST]: Add "Exit Preview Mode" Option for Surveys

[JiyaGupta-cs]

Current Behavior:

While exploring the features of the dashboard, I encountered an issue, when users enter the "Preview Mode" for a survey, there is currently no visible option to exit the preview mode. This causes confusion as users have no clear way to return back to the editing mode.

Desired Behavior:

An "Exit Preview Mode" button should be available, allowing users to easily exit the preview mode and return back to the editing mode.

Steps to Reproduce

• Navigate to the survey page at /survey
• Click on "Edit Survey"
• Click on "Preview Survey"

Proposed Solution

• Add a clearly visible "Exit Preview Mode" button in the preview interface.
• Position the button prominently at the bottom of the page along with the "Preview Mode" label.

Impact

• Improves user experience by providing an intuitive way to navigate between modes.
• Reduces confusion for users previewing surveys.
