Feature: Undo Redo options multi tool #2297 (#2348)

* Implement Command class for Command Pattern

Created a base `Command` class to implement the **Command Pattern**. This class provides a skeletal implementation for `execute`, `undo`, and `redo` methods.

**Note:** This class is intended to be subclassed and not instantiated directly.

* Add undo/redo stacks and operations

* Use rotate element command to perform execute/undo/redo operations

* Handle commands executed through events
- Add "command-execution" event listener to execute commands that are not invoked from the same class while adding the command to the undo stack and clearing the redo stack.

* Add and use rotate all command to rotate/redo/undo all elements

* Use command pattern to delete pages

* Use command pattern for page selection

* Use command pattern to move pages up and down

* Use command pattern to remove selected pages

* Use command pattern to perform the splitting operation

* Add undo/redo functionality with filename input exclusion

- Implement undo (Ctrl+Z) and redo (Ctrl+Y) functionality.
- Prevent undo/redo actions when the filename input field is focused.
- Ensures proper handling of undo/redo actions without interfering with text editing.

* Introduce UndoManager for managing undo/redo operations

 - Encapsulate undo/redo stacks and operations within UndoManager.
- Simplify handling of undo/redo functionality through a dedicated manager.

* Call execute on splitAllCommand

- Fix a bug that caused split all functionality to not work as execute() wasn't called on splitAllCommand

* Add undo/redo buttons to multi tool

- Add undo/redo buttons to multi tool
- Dispatch an event upon state change (such as changes in the undo/redo stacks) to update the UI accordingly.

* Add undo/redo to translations

* Replace hard-coded "Undo"/"Redo" with translation keys in multi tool
