Feature Request: Private Contests with Custom Problem Setting Capabilities

summary

I would like to request a feature that allows users to create and host private contests on Repovive. This would be incredibly useful for conducting internal coding events, specifically for schools and colleges. I conducted a small contest on my college last week, it was on repovive editor with saving each code and testing manually I wish some feature existed

Proposed Functionality

1. Create a Private Lobby: Generate a contest link/code that only invited participants can join.
2. Authour Custom Problems: We need a UI to write our own problem statements (Description, Input/Output format, Constraints).
3. Upload Custom Test Cases: This is critical. We need the ability to upload our own hidden test cases and sample cases to grade the solutions automatically using Repovive's judge.
