[FIX] web: Layout's display props could be dynamic

Before this commit, if the Layout's `display` props is a dynamic value
coming from the parent Component (ie. a getter on the component that
controls which parts of the ControlPanel should be displayed), this
value isn't applied after the first initialization.

This commit fixes it by extracting the `display` logic applied in the
constructor to a getter (moving from initialization only to once
called).
