Leaderboard for Player Rankings Against AI Opponents

[SverreNystad]

This task involves creating a leaderboard system to rank players based on their performance against AI opponents in our games. The leaderboard should provide a competitive and motivating environment for players, encouraging them to improve their skills and climb the rankings.

Acceptance Criteria:

• The leaderboard is implemented and accurately ranks players based on their performance against AI opponents.
• There is a reachable page for looking up the leaderboard
• The leaderboard is persistent even after restarting the backend

This will require data storage, either writing to a file or a database like Postgres. If we implement this as well we will effectively have made an application that would be fit for a subject like IT1901 - Informatics, Project I in two days xD

I do not yet know what exactly we should measure when dealing with performance. It could be rounds survived and or how few turns were used to win over specific agents. We could maybe have a table that one can order based on agent and amoute of turns
