* fix(panels): keep desktop runtime config alert hidden when disabled
* refactor(panels): let render() own visibility in alert-mode show()
Removes the unconditional setEffectiveVisibility(true) before render() in
the show() override. For alert mode, render() already decides visibility
based on config state — calling setEffectiveVisibility(true) first meant
the element briefly appeared then was immediately re-hidden for fully-
configured panels. Non-alert mode is unchanged.
