## Summary by CodeRabbit
* **Refactor**
* Replaced legacy context-menu component variants with the unified UI
context-menu components across the app for consistent rendering and
imports; behavior and menu content remain unchanged.
* **Tests**
* Updated a test mock to track the unified context-menu component mount
count.
* **Chores**
* Simplified UI package re-exports to expose the canonical context-menu
symbols.
