feat(data-modeling): add undo/redo application menu interactions COMPASS-9976

[addaleax]

Split into two PRs (this one and #7493) for easier review and because I'm honestly quite sure that we want to do #7493, but the data-modeling specific parts add a bit of complexity that we should agree is worth it before we merge

chore: refactor and centralize app menu access (#7493)

Instead of having the logic for accessing the Electron application menu
from the collection tabs spread out through the codebase, bundle it
in a single interface that gives all Compass plugins access to
the menu as needed.

feat(data-modeling): add undo/redo application menu interactions

This requires adding some machinery to track whether undo/redo
events should apply to the current diagram (by testing whether
no element outside of the diagram is focused), as well as
accounting for the fact that the diagram also has hotkey handlers
that can be triggered by the same keyboard presses.

Pull Request Overview

This PR adds undo/redo functionality integration with the Electron application menu for the data modeling diagram editor. The implementation ensures that undo/redo operations triggered from the application menu only apply when the diagram editor has focus, and handles the case where the same keyboard shortcut might trigger handlers from both the hotkey listener and the application menu.

Key changes:

• Added focus state tracking to determine when the diagram editor should respond to menu commands
• Implemented debouncing logic to prevent duplicate handler invocations from multiple event sources
• Integrated application menu handlers for undo/redo operations
