Right click vue nodes (#5790)

This pull request refactors and improves the "More Options" popover
functionality for graph nodes in the UI. The main change is a rename and
redesign of the menu component from `MoreOptions` to `NodeOptions`,
introducing a global singleton pattern for popover control and enabling
context menu support on node right-click. This results in better
maintainability, more flexible triggering, and improved user experience.

**Node Options popover refactor and global control:**

* Renamed and refactored `MoreOptions.vue` to `NodeOptions.vue`,
removing the embedded button and exposing imperative methods (`toggle`,
`hide`, `isOpen`) for external control. The component now
registers/unregisters itself globally via `registerNodeOptionsInstance`.

* Added `NodeOptionsButton.vue` as a dedicated button component for
triggering the popover, decoupling the button UI from the popover logic.
* Implemented a global singleton pattern in `useMoreOptionsMenu.ts` for
controlling the `NodeOptions` popover from anywhere, with
`toggleNodeOptions` and `registerNodeOptionsInstance` functions.

**UI integration and event handling improvements:**

* Updated `SelectionToolbox.vue` to use the new `NodeOptionsButton`
instead of the previous embedded `MoreOptions` button, and added the
`NodeOptions` popover to the main `GraphCanvas.vue` template for global
accessibility.

* Added right-click context menu support to `LGraphNode.vue`, triggering
the node options popover at the cursor position and integrating with
node selection logic.

**Minor improvements and cleanup:**

* Updated references and variable names throughout the codebase to
reflect the new `NodeOptions` naming and logic.

This refactor makes the node options menu more modular, easier to
maintain, and more flexible for future UI improvements.
