⚡ Bolt: Optimize SwiftUI View Model Array Batching

[acebytes]

💡 What: Used functional map to batch updates into single property assignments.
🎯 Why: Mutating elements of @Published arrays inside a loop triggers a UI update notification for every change.
📊 Impact: Reduces unnecessary UI recalculations to exactly 1 update per operation instead of O(n).
🔬 Measurement: Verify by observing reduced CPU usage or instrumenting view renders during bulk select operations.
