Replaces every em-dash and en-dash with regular ASCII hyphens across comments, JSX strings, and dev-facing logs. Mostly cosmetic but stops the inconsistent mix that crept in over the last few months (some files used em-dashes in comments, others didn't, some used both). Bundles two small dashboard-layout tweaks that touch a couple of already-modified files: - (dashboard)/layout.tsx main padding goes from p-6 to pt-3 px-6 pb-6 so page content sits closer to the topbar. - Sidebar now receives the ports list it needs for the footer port switcher.
