[Feature Request] Display total file counts for rounds in the Admin Dashboard

[ayushshukla1807]

Problem

Currently, organizers and coordinators cannot easily see the total number of files/entries in a round from the Admin Dashboard view without clicking into the round details. This makes it difficult to quickly assess the scale of different rounds at a glance.

Proposed Solution

Safely expose the total_entries count in the Round.to_info_dict() method and display it in the RoundView.vue component next to the round status.

Benefits

• Better visibility for organizers.
• Faster assessment of campaign progress.
• Consistent UI with other metrics.
