ScriptBodyEditor: overlay now has overflow-hidden and syncs scroll
position from the textarea via onScroll, so only one scrollbar appears.
ScriptManagePage: outer scroll container is now full-width so scrolling
works even when hovering outside the max-w content area.

Add pulsing cyan dot + hover gear rotation to make the link noticeable.
Add overflow-y-auto to ScriptManagePage so the editor form scrolls.
