Fix report builder flashing on every column toggle

Remove redundant dispatch('refreshTable') from updatedSelectedColumns()
since Livewire already re-renders when the property changes. Increase
checkbox debounce from default 150ms to 500ms so rapid toggles are
batched into fewer requests.

Closes #101
