Move Settings out of the right-side overlay into a left-nav page (page='settings'),
so it opens where you're already looking — no cross-screen mouse travel. The Settings
rail item now sets the page (with active highlight) instead of opening a dialog; the
panel is refactored to an in-flow .glass card (keeps the frosted look over the ambient
backdrop), with the page title shown in the header. Removed the overlay + Esc/backdrop
close path.
