Refactor currency-per-kill functionality to use a cron job and query events

[takaro-ci-bot]

Description

Refactor the current currency-per-kill functionality to use a cron job that queries events instead of firing a function for every zombie kill. This will significantly reduce the load on the system and the number of functions being executed.

Requirements/use-cases

• Implement a cron job that runs every 10 minutes
• Query all zombie kill events for the last 10 minutes
• Calculate and distribute currency based on the queried events
• Ensure this method is more efficient than the current implementation

Implementation details

• Use the events API to query zombie kill events
• Utilize the new 'greater than' operation for event searching (e.g., created_at greater than 10 minutes ago)
• Aggregate kills per player and distribute currency accordingly
• Consider implementing this as a built-in module for easy user adoption

Benefits

• Reduced system load
• Lower function execution count
• More scalable solution for high-traffic servers
• Potentially lower costs for users
