[FIX] web: graph rendering when in DOM

Backported fixes:

    1. [IMP] web: GraphView: remove hack to render in DOM

        - ref. 166319fa
        - fully backported.

This commit backports the fix that removes the hack for rendering graphs
(delay in a setTimeout), so that the graph is rendered when it is in the DOM.

    2. [IMP] web: restore scroll position

        - ref. 4e204ed2
        - partially backported: only keeps `on_attach_callback`
          and `on_detach_callback` in the abstract_controller
          and in the abstract_renderer.

This commit backports the use of the hooks methods `on_attach_callback` and
`on_detach_callback` in abstract controller and renderer, so that the
controller of any view warns the renderer when it has been attached in
(or detach from) the DOM.

Also, this commit adds `on_attach_callback` and `on_detach_callback` for the
dashboard app, so that the graph view is correctly rendered.
