Closes #483

Summary

Fixes the StudyPlan CSV export flow by preventing automatic downloads when users click the Download Data sidebar option. Users must now explicitly confirm the export before the CSV file is generated.

Changes Made

• Removed immediate CSV download trigger from sidebar selection
• Added export confirmation panel/modal for download action
• Added dedicated Download CSV button
• Separated navigation action from export action
• Added protection against duplicate downloads from repeated clicks
• Added loading/disabled state during export process
• Preserved existing CSV export functionality and file format
• Improved overall user experience and predictability

Testing

Tested locally using the following scenarios:

• Opened StudyPlan application
• Navigated to sidebar and clicked Download Data
• Verified no automatic download occurs
• Verified export panel/modal opens correctly
• Clicked Download CSV and confirmed CSV downloads successfully
• Repeated sidebar clicks and confirmed duplicate files are not created
• Tested modal close/cancel behavior
• Checked browser console for errors

Screenshots

After changes

Before
