refactor(code): move insertStringAndSaveChange to InsertUtil

Consolidate the `insertStringAndSaveChange` function into `InsertUtil` to reduce code duplication and improve maintainability. This change involves removing the function from multiple files and ensuring it is properly imported and used where needed. Additionally, a validation check for `startOffset` was added to prevent out-of-bounds errors.
