fix: context menu uses Alpine proxy (window._wsData) instead of raw object

The context menu component (_ctxMenuData) was calling methods on
window._wsInitData (the raw JS object), NOT on Alpine's reactive proxy.
This meant that changes made by ctxMenuDelete/ctxMenuDuplicate (like
updating displayTree) were applied to the raw object but not reflected
in Alpine's reactive proxy that controls DOM rendering.

Fix: _ctxMenuData now uses a _ws() helper that returns window._wsData
(Alpine proxy, set in init()) with fallback to window._wsInitData for
safety. All context menu actions now go through the reactive proxy.
