⚡ Bolt: [performance improvement]

[yeboster]

What: Replaced Array.prototype.includes() with Set.prototype.has() in the array filtering logic for the voters add/remove API endpoints.
Why: Using includes() inside a filter() callback creates an O(N*M) time complexity which can become a bottleneck when dealing with potentially large arrays of voters and owners.
Impact: Reduces the time complexity to O(N+M) by precomputing a Set, resulting in significantly faster execution times for these endpoints when processing large data sets.
Measurement: The improvement can be verified by observing lower CPU time and execution duration when invoking these endpoints with a large number of voters and owners.
