fix: menu contextuel en DOM natif (bypass Alpine)

Alpine ne détecte pas les changements sur ctxMenu (objet imbriqué
hors du scope _wsInitData dans le DOM). Le :style et x-show restent
bloqués sur les valeurs initiales.

Solution radicale: manipulation DOM directe
- onContextMenu: menu.style.display='block' + position left/top
- ctxMenuOpen*/Rename/Duplicate/Delete: menu.style.display='none'
- @click.outside/@keydown.escape: DOM direct aussi
- ctx-menu HTML: style="display:none" initial
