fix: sync body class after htmx-boosted navigation (issue #168)

HTMX boost swaps <body>'s innerHTML only, never its own class attribute. Navigating from an app-shell page (overflow:hidden, scroll handled by an inner column) to a non-app-shell page left the stale app-shell class in place with no matching inner scroll container, making the page completely unscrollable until a hard refresh. Fixed by exposing the resolved body_class as a data attribute on #content (which does get freshly rendered on every boosted swap) and re-syncing document.body.className from it on every htmx:afterSettle.
