Fixes https://github.com/twentyhq/twenty/issues/8970
The context menu wasn't working because of wrong architecture with the
Dropdown component, as it's a unique behavior (no clickable component
and portal) it also required refactoring a bit the Dropdown component.
- Context menu now uses a portal
- Fixed dropdown offset without clickable component (now using a
fallback anchor component)
- Fixed React array key props
