[BEGINNER FRIENDLY] Replace latest-report placeholder export button on Reports page

[utksh1]

Summary

The Reports page header still has a latest briefing export button that points at a placeholder latest-report route. It should either target the newest ready report or be removed/disabled with clear behavior.

Scope

• Update frontend/src/pages/Reports.tsx.
• Prefer using the newest report with status ready from the reports data.
• Add/update unit tests around the header export button behavior.

Acceptance Criteria

• The button never calls /task/latest/report/pdf.
• If a ready report exists, it opens that report's PDF URL.
• If no ready report exists, the button is disabled or hidden.
• Existing per-report export buttons keep working.

Hi @utksh1

I would like to work on this issue under GSSoC'26.

I understand that this task focuses on replacing the placeholder latest-report export behavior with a proper dynamic report export flow.

My implementation approach would include:

• Updating frontend/src/pages/Reports.tsx
• Detecting the newest report with ready/completed status
• Replacing the placeholder export route with the actual latest ready report PDF URL
• Disabling or hiding the export button when no ready report exists
• Ensuring existing per-report export functionality remains unaffected
• Adding/update unit tests for the new export button behavior

I’ll ensure the implementation stays clean, reliable, and aligned with the current frontend architecture and UX patterns.

Please assign this issue to me. Thank you!
