fix: resolve PHPStan array key type errors

- Fix invalid array key type in CollectionDataTable::revertIndexColumn()
- Fix invalid array key type in DataTableAbstract::with()
- Fix instanceof and array key type issues in DataTables::make()
- Fix invalid array key type in DataProcessor::process()
- Fix invalid array key types in Helper::includeInArray()

All fixes ensure array keys are properly typed as int|string to satisfy PHPStan's strict type checking.
