Right-click menu enhancements

A flatter, keyboard-friendly right-click menu.

The DBE Navigator context menu open on a main element, with Duplicate focused and grouped actions for copy, paste, rename, insert, move, components and removal.
The enhanced context menu keeps common actions visible and groups the rest by task.

Reorganises the Navigator right-click menu around the actions used most often, with compact flyouts for inserting, moving and advanced tools. Includes full keyboard support (arrow keys, Home/End and Escape); unavailable commands remain discoverable and explain why they cannot currently run. Also adds a right-click copy and remove menu to the class chips in the Styles editor.
